Title:
RESONANT LOAD POWER CONVERSION DEVICE AND TIME DIVISION OPERATION METHOD FOR RESONANT LOAD POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104337
Kind Code:
A1
Abstract:
Provided is a resonant load power conversion device in which the switching frequency of each switching element can be reduced, and the number of main circuit conductors can be reduced. This resonant load power conversion device is equipped with: a single-phase inverter, the DC input side (Vdc) of which is connected to a DC voltage source and the output side (Vout) of which is connected to a resonant load, and which outputs a rectangular voltage at a resonant frequency; switch group circuits 100U, 100X, 100V, 100Y, which are connected respectively to upper and lower arms on the input side and the output side of the single-phase inverter, and each of which has N (N being an integer of 2 or more) series bodies having two switching elements and connected in parallel, with the switching elements being connected to each other by main circuit conductors; and a control unit, which controls the switching of the switching elements (U11-U32, V11-V32, X11-X32, Y11-Y32) of the switch group circuits 100U, 100X, 100V, 100Y in a time-division manner.
