Title:
SYSTEM AND METHOD FOR HIGH EFFICIENCY WIDE-VOLTAGE-GAIN POWER CONVERSION
Document Type and Number:
WIPO Patent Application WO/2024/055031
Kind Code:
A3
Abstract:
A high efficiency wide-voltage-gain power conversion system and method is disclosed. The system includes a variable-inverter-rectifier-transformer (VIRT) having four pairs of switches forming four half-bridges. Each pair of switches has a top and bottom switch, with the top switch being in one state of "on" and "off" and the bottom switch being in the other state. The states of the four pairs is described by a vector associated with a segment voltage output by the VIRT. The system also includes a converter having a transformer communicatively coupled to the VIRT such that cycling the VIRT through a sequence of vectors generates a waveshape that drives a flux inside a center post of the transformer. The VIRT interfaces with a first voltage, and the converter interfaces with a second. At least one of the input and output voltages varies across a wide voltage range.
