Document Type and Number:
Japanese Patent JP2017112732
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric power conversion system for a resonance load, capable of decreasing a switching frequency of each switching element, and reducing the number of a main circuit conductor.SOLUTION: An electric power conversion system for a resonance load, comprises: a single phase inverter in which a DC input side (Vdc) is connected to a DC voltage source and an output side (Vout) is connected to the resonance load, and which outputs a rectangular wave voltage in a resonance frequency; switch group circuits 100U, 100X, 100V, and 100Y that are connected to upper and lower arms of an input side and the output side of the single phase inverter, and in which a series body of N (N is two or more integer numbers) of two switching elements is connected in a main circuit conductor between switching elements in parallel; and a control part that executes the switching control of each switching element (U11 to U32, V11 to V32, X11 to X32, and Y11 to Y32) of switching group circuits 100U, 100X, 100V, and 100Y by time division.SELECTED DRAWING: Figure 1
