Hillcrest’s ZVS inverter platform is engineered to meet these demands by improving not just component-level performance, but the entire power conversion system. Wide bandgap (WBG) semiconductors like silicon carbide (SiC) and gallium nitride (GaN) have opened the door to smaller, faster, and more efficient inverters.
As electrification accelerates across mobility, renewable energy, and industrial systems, Hillcrest Energy Technologies is offering a smarter path forward. Our proprietary Zero Voltage Switching (ZVS) inverter technology unlocks new levels of efficiency, performance, and integration — all while reducing complexity and cost.
The experimental results of a 1-kVA prototype verify that the proposed inverter features a high voltage gain, ZVS of all switches, high conversion efficiency, high output power quality, and strong load adaptability and has an important prospect in single-phase inversion with low input voltage or wide input voltage range.
Additionally, all of the diodes turn off with ZCS, which effectively minimizes the reverse-recovery losses. When compared to traditional ZVS converters, the voltage ratings of the switching components are significantly reduced due to lower voltage stress values. The voltage gain is doubled in comparison to the traditional boost converter.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
