Technology

The invention proposes a converter architecture that uses "Variable Frequency Multiplier" (VFX) inverters and rectifiers and associated controls to achieve extreme high-efficiency conversion across a wide range of operating conditions in terms of input and output voltages and power levels. VFX circuits are high-frequency inverters and/or rectifiers that change operating modes to provide "gear shifts" that increase the range for which high-efficiency operations are maintained.
