Hillcrest Energy Technologies Finalizes A-Sample Design of Zvs Pcs1000 Sidecar Power Unit for Next-Generation Ai Data Centers Hillcrest Energy Technologies Ltd. has finalized the A-Sample design of its ZVS PCS1000 Grid Power Conversion System, a purpose-built 250 kW, 800V DC sidecar rectifier module developed for next-generation AI data center infrastructure. The A-Sample design finalization is a key engineering milestone, confirming the product architecture, form factor, and performance specifications ahead of the prototype demonstration program planned to begin in June 2026. The ZVS PCS1000 A-Sample has been designed in a 19", 4 rack unit (4RU) form factor supporting both liquid cooling and forced air, targeting 250 kW maximum continuous power output at 800V DC, with a modular architecture supporting scalability from 200 kW to 1,200 kW or greater through parallel units. The design incorporates N+1 redundancy with 25% extra capacity and hot-swap capability intended to support 24/7 operational availability in mission-critical AI compute environments. The ZVS PCS1000 is designed to align with the Open Compute Project (OCP) 800V data center sidecar power architecture, converting 400/480V AC grid power to 800V DC for direct distribution to IT racks at up to 1,500A. The OCP sidecar power architecture is defined in the Mt. Diablo specification, published by the Open Compute Project Foundation in October 2025. The ZVS PCS1000 incorporates grid fault ride-through (FRT) capability, enabling the power conversion system to remain electrically connected during short-duration voltage and frequency disturbances. Without FRT, such grid events can lead to cascading load disconnections and subsequent system instability. By integrating FRT, the ZVS PCS1000 helps stabilize grid behavior by maintaining electrical coupling and ensuring smooth power transitions during transient conditions. The ZVS PCS1000 A-Sample design targets 200–250 kW in a 19" form factor, which the Company believes provides a high-power density solution with the potential to reduce the total number of modules required per sidecar deployment and lower overall system cost. The PCS1000’s performance targets are based on Hillcrest’s proprietary Zero Voltage Switching (ZVS) topology, which the Company believes offers the following design advantages versus conventional hard-switched converters: Hillcrest’s ZVS topology eliminates switching losses by ensuring power transistors transition at zero voltage. The ZVS PCS1000 A-Sample design targets peak conversion efficiency exceeding 99% — compared to the 98% typical of hard-switched designs. Hillcrest’s ZVS technology has been independently validated through testing completed at facilities of global automotive OEMs and suppliers. Those tests confirmed 99.7% peak inverter stage efficiency, with greater than 99% efficiency maintained across 90% of the full operating range — results first publicly disclosed in the Company’s December 16, 2024, news release. The PCS1000 is built on the same underlying ZVS platform validated in those tests. Hillcrest’s ZVS technology produces significantly lower dV/dt than hard-switched designs, as first publicly disclosed in the Company’s March 4, 2024, news release. Certified lab radiated EMI testing of the ZVS switching stage, conducted without any EMI filter in place, showed radiated emissions below applicable pass limits. These results demonstrate the intrinsic EMI advantage of the ZVS topology and are expected to reduce filter complexity and cost in the ZVS PCS1000 A-Sample design. Lower switching losses are expected to reduce junction temperatures and thermal cycling in power semiconductors, supporting simplified cooling architecture and reduced thermal stress on power semiconductor components. The ZVS PCS1000 design operates at 48 kHz — approximately four times the practical ceiling of thermally-limited hard-switched designs — which is expected to reduce passive component size by up to 50% and contribute to its power density in the 19” form factor. The ZVS PCS1000 prototype remains on track, with customer and partner demonstrations being scheduled starting in June 2026 at Hillcrest’s facility in Vancouver, British Columbia and at Systematec GmbH’s facility in Germany. The Company is currently in active discussions with several parties across the data center, energy storage, and grid-connected applications markets regarding demonstration opportunities. There is no assurance that these discussions will result in commercial agreements. Announcement • Apr 07

Hillcrest Completes Technology Evaluation Project with Global Tier 1 Automotive Supplier Hillcrest Energy Technologies announced the successful completion of Phase 1 of its technology evaluation project with a global Tier 1 automotive supplier. The project successfully demonstrates the technical feasibility of converting the supplier's half-bridge power modules to enable Zero Voltage Switching (ZVS) operation for next-generation electric vehicle (EV) inverter applications. ZVS Evaluation Complete. The global Tier 1 automotive supplier involved in this evaluation is consistently ranked among the top 15 largest by revenue and is a recognized leader in automotive electrification. Specializing in critical power electronics components including inverters for electric vehicles, the supplier serves major automotive manufacturers worldwide and provided an optimal validation framework for this ZVS technology integration project. In March 2025, Hillcrest announced the commencement of this project, with the Phase 1 objective being to develop the conversion of the supplier's half-bridge Power modules to enable ZVS operation, with the aim of assessing the potential efficiency and performance of Hillcrest's technology on the Tier One Supplier's inverter architecture. Hillcrest successfully completed all requirements of the Phase 1 project and demonstrated technical viability through baseline measurements, hardware design, production and assembly of prototypes, double pulse testing, and final hardware delivery. The Open Compute Project, supported by major technology leaders including Meta, Microsoft, Intel and NVIDIA, is standardizing 800V DC distribution to handle AI workload power densities that are reshaping facility requirements. Traditional data center power architectures face significant limitations as AI computing demands escalate. Conventional systems route power through multiple conversion stages-introducing substantial inefficiencies where each conversion stage generates heat and consumes valuable space. The ZVS PCS1000 addresses these challenges through streamlined 800V DC architecture that eliminates intermediate conversion stages, with power flowing directly from medium voltage grid to 800V DC through the ZVS PCS1000, then through isolated DC-DC converters to computing loads. This modular scalability allows data center operators to match power infrastructure precisely to computing requirements while maintaining flexibility to expand capacity as AI workload demands grow. The Company recently released a white paper quantifying component-level advantages enabled by ZVS technology. ZVS-optimized inductors demonstrate cost reductions of up to 75% compared to conventional designs, with weight reductions of up to 4x and volume reductions of up to 3.3x. In data center applications where space commands premium value, these reductions translate to measurable capital savings and enable more flexible facility layouts. The Company is establishing strategic partnerships to accelerate these grid-connected applications, including advanced discussions with Pasqua First Nation and Apeiron Resources Ltd. regarding Canadian manufacturing and commercialization of ZVS grid inverter products. The partnership structure is expected to emphasize meaningful economic participation, energy sovereignty, and community ownership, with target markets spanning energy storage systems, AI data centers, industrial applications as well as remote microgrids. Value Creation Through Strategic Prioritization. Hillcrest's strategic approach focuses resources on opportunities offering the highest probability of near-term commercial success and substantial value creation. In automotive applications, this means prioritizing licensing and partnership discussions with parties demonstrating strong commercial commitment and clear paths to technology deployment. In grid-connected applications, this means focusing product development and customer engagement on markets where ZVS technology delivers quantifiable economic advantages and where customer needs align with the Company's technical capabilities and development timeline.
