Document Type and Number:
WIPO Patent Application WO/2018/198888
Kind Code:
A1
Abstract:
An inverter (10, 110, 120) has upper arm elements (11-13, 111-113, 211-213) and lower arm elements (14-16, 114-116, 214-216), converts power supplied from a direct current power supply (5) via power wiring (17, 117, 217), and supplies power to a load (80). A driver (30) is supplied with power from the direct current power supply (5) via control wiring (75), and applies a gate voltage to the upper arm elements and the lower arm elements. Each of control units (41-44) has a drive control unit (60) that controls operations of the upper arm elements and the lower arm elements corresponding to a current command value. The direct current power supply (5) supplies power also to a device (4) in addition to the inverter (10, 110, 120). Corresponding to the gate voltage or corresponding to an input voltage and the gate voltage, the control units (41-44) limit a current flowing to the load (80).
