Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/203143
Kind Code:
A1
Abstract:
[Problem] To provide a power conversion device with which it is possible to smoothly supply a compensation current that cancels out a leakage current from a load, using an available and relatively simple configuration, without specially using a high-withstand-voltage transistor as a complementary transistor. [Solution] A compensating current supply circuit 17, having: a complementary transistor 18 having commonly connected bases and commonly connected emitters; resistance voltage divider circuits 21, 22 for voltage-dividing a DC power supply and applying the divided voltages respectively between the emitter and collector of transistors Tr1, Tr2 that constitute the complementary transistor 18; and coupling capacitors Cs respectively connected between the DC power supply and the collector of each of the transistors.
