Title:
POWER CONVERSION DEVICE AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2024/100430
Kind Code:
A1
Abstract:
The present invention provides a method for controlling a power conversion device (1) comprising: an inverter circuit (2) which has a first switch (Q1) and an LC resonant circuit (5) and which outputs AC power; a rectifier circuit (3) which has a first rectifier element (D1) and a choke inductor (L2) and which converts AC power input from the inverter circuit (2) into DC power for output; a switching circuit (4) which has a second switch (Q2) and a second rectifier element (D2) and which is connected to the output of the rectifier circuit (3); and a control unit (8) that controls the operations of the first switch (Q1) and the second switch (Q2). The control unit (8) manipulates the time ratio of the second switch (Q2) on the basis of the output voltage of the power conversion device (1).
