Title:
CONTROL DEVICE FOR POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2017034862
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a power conversion device capable of improving a power supplying speed while suppressing an excessive current in a circuit.SOLUTION: A control device 300 for a push-pull type power conversion device comprising a first switching element Q11, a second switching element Q12, and a choke coil L13, comprises: a current detection unit 103 that detects a current value of the choke coil L13; and an input voltage detection unit 102 that detects a voltage applied from a DC power supply 100. First control of turning ON both the first and second switching elements Q11 and Q12, second control of turning ON one of the first and second switching elements Q11 and Q12 and turning OFF the other, and third control of turning OFF both the first and second switching elements Q11 and Q12, are sequentially repeated. Switching from the first control to the second control is performed on the basis of the fact that the current value becomes a command value. The command value is set on the basis of a voltage.SELECTED DRAWING: Figure 1
