Title:
POWER SUPPLY CIRCUIT AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/116695
Kind Code:
A1
Abstract:
In order to improve stability of output from a power supply circuit, this power supply circuit comprises switching element pairs (10A, 10B), which comprise high-side switching elements (Q1, Q3) and low side switching elements (Q2, Q4) connected in series to said high-side switching elements, and a control unit (2), which drives the switching elements configuring the switching element pairs in a complementary manner; the control unit (2) controls the on/off state of the switching elements such that the switching duty of the high side switching elements and the low side switching elements during a first period (steady state operation) differs from the switching duty of the high side switching elements and the low side switching elements during a second period (Q1 drive voltage holding operation).
