Document Type and Number:
WIPO Patent Application WO/2021/100872
Kind Code:
A1
Abstract:
[Problem] To provide a single-direction insulative DC-DC power converter using a single-direction switch circuit capable of realizing soft switching even with a simple circuit configuration and a method for controlling the DC-DC power converter. [Solution] A power converter comprising a primary circuit and a secondary circuit connected via a high-frequency transformer, wherein a circuit having a switching element is provided to the primary circuit, the secondary circuit has, connected in parallel, a DC capacitor and a diode rectifying circuit including four diodes U+, U-, V+, and V- each having a resonance capacitor Cr connected in parallel, and a resonance circuit formed by the resonance capacitor Cr and a leakage inductance L of a the high-frequency transformer is formed in the secondary circuit.
