Title:
POWER CONVERTER AND POWER CONVERSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/181361
Kind Code:
A1
Abstract:
A power converter according to an aspect of the present invention comprises: a first power terminal; a switching unit; a transformer; a rectification unit having a switching circuit including first and second switching elements; a smoothing unit; a second power terminal; a control unit; and a drive unit capable of driving the switching circuit. The switching circuit has a first element provided in a first path connecting a control terminal with a first terminal of the first switching element and capable of clamping a voltage. The drive unit can output a first control signal from a first output terminal and output a second control signal from a second output terminal. The control unit can control the operation so that power is supplied from the second power terminal toward the first power terminal in a period different from a period during which power is supplied from the first power terminal toward the second power terminal, and can also set the output impedance of the first output terminal in the drive unit to a high impedance state.
