Title:
LOAD DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/108501
Kind Code:
A1
Abstract:
The disclosed load driving device is provided with a converter which has two switching elements connected in series and which converts the DC voltage outputted by a capacitor to a DC voltage of a different level, an inverter which converts the DC voltage outputted from the converter to an AC voltage and applies the same to a rotary inductive load, and a condenser arranged in parallel with and between the converter and the inverter. One of the two switching elements configuring a portion of the power supply path from the capacitor to the rotary inductive load is a normally-on type semiconductor element. As a consequence, the power generated by regenerative operation of the rotary inductive load can be stored in the capacitor by means of a simple structure even if the control unit or the converter fail.
