Title:
POWER CONVERSION DEVICE AND FLYING OBJECT
Document Type and Number:
WIPO Patent Application WO/2024/105872
Kind Code:
A1
Abstract:
This power conversion device comprises: a main inverter (9) that can output voltages having at least three levels; a sub-inverter (12) that is connected to the output of the main inverter (9), has a plurality of semiconductor switching elements (Q13, Q14, Q15, Q16) and an intermediate capacitor (10U), and adjusts the voltage of the intermediate capacitor (10U) to the output voltage of the main inverter (9); and a control unit (19) that controls the main inverter (9) and the sub-inverter (12). The control unit (19) performs a PWM control so that the losses of the plurality of semiconductor switching elements (Q13, Q14, Q15, Q16) of the sub-inverter (12) become equal.
