POWER CONVERSION DEVICE, AND COOLING AIR CONDITIONING DEVICE

摘要

Provided is a power conversion device configured to convert electric power from a power source 1 to a load 9, including: a boosting device 2 including a boost rectification unit 23 configured to prevent backflow of a current from the load 9 side to the power source 1 side, the boosting device 2 being configured to change a voltage of power from the power source 1 to a predetermined voltage based on a drive signal; a commutation device 4 configured to perform commutation operation in which a current flowing through the boosting device 2 is caused to flow into an other path based on a commutation signal; and a signal generating module device 200 configured as a module to generate and send an output signal based on an input signal that is input thereto. The input signal has an on-pulse width greater than a length of time where the output signal generated by the signal generating module device 200 is turned on.
