This reference design utilizes a buck-converter topology to precharge large high-voltage (HV) DC- link capacitances in hybrid electric vehicles (HEV), electric vehicles (EV), and energy storage systems (ESS). This design expands upon and updates High-Voltage Solid-State Relay Active Precharge Reference Design.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
