The Vicor ultra-high voltage bus converter modules (UHV BCMs) are 400 VIN to 700 VIN power components that provide voltage transformation, current multiplication, and isolation. UHV BCMs are uniquely suited for designs that require high power density, high efficiency, small size, and low weight. They are commonly used in three-phase AC Industrial power and DC transmission systems for remote unmanned vehicles.
Using the Vicor resonant Sine Amplitude Converter™ (SAC) topology, the UHV BCM leverage high-frequency zero-voltage switching (ZVS) and zero-current switching (ZCS) to deliver unmatched efficiency and power density with low noise and fast transient response. Also, its low AC impedance, beyond the bandwidth of most downstream regulators, enables bulk capacitance, normally located at the input of a regulator, to be placed at the high voltage input to the BCM. This reduces bulk capacitance requirement saving board area and lowering system cost.
