摘要
The present invention relates to a DC-DC converter for power supply used in an inverter of an anti-start air conditioner compressor when an air conditioner of a commercial vehicle is used. The L-C resonant DC-DC converter for an anti-start air conditioner compressor for a commercial vehicle comprises: a high frequency transformer increasing an input voltage of a battery and outputting the voltage; a switch unit having first, second, third, and fourth switches on a first side of the high frequency transformer in a full-bridge form and providing a battery voltage to the high frequency transformer by switching according to an input signal; a rectifying unit formed on a second side of the high frequency transformer, having first and second diodes and first and second capacitors, and rectifying the voltage increased by the high frequency transformer; and a control unit receiving an output voltage output from the rectifying unit and turning on or off the first to fourth switches. The L-C resonant DC-DC converter for an anti-start air conditioner compressor for a commercial vehicle can reduce a switching loss of the switch unit by performing resonation at a resonance frequency of first and second capacitors and the leaked inductance of the high frequency transformer.
