Title:
POWER CONVERSION DEVICE AND CONTROL DEVICE THEREOF
Document Type and Number:
Japanese Patent JP2020096517
Kind Code:
A
Abstract:
To control both an AC/DC conversion circuit and a DC/AC conversion circuit.SOLUTION: A control device 100 is used as a control body of a power conversion device 1 including a switch circuit 10 including transistors M1 to M4, and subtracts a multiplication signal (=K×I) obtained by multiplying a control target current I of the switch circuit 10 by a predetermined coefficient K from a reference signal REF according to an operation mode MODE (PFC/INV) of the power conversion device 1, and generates control signals S1 to S4 (and thus gate signals G1 to G4) of the transistors M1 to M4 on the basis of the calculation result (=REF-K×I).SELECTED DRAWING: Figure 1
