Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026141
Kind Code:
A1
Abstract:
A power conversion device according to the present invention converts a DC voltage output from a DC power supply into an AC voltage in a current discontinuous mode. A current controller (6) calculates a target voltage value (VL*) between both ends of a reactor such that a value of current (Iinv) flowing through the reactor becomes a target current value (Iinv*). In the current discontinuous mode, a nonlinear compensator (701) calculates a target conduction ratio (D*) of a current sampling time by using the target voltage value (VL*), a target conduction ratio (D*) before one sampling time, and an output voltage value (Vc) before one sampling time.
