DC-DC CONVERTER FOR POWER SUPPLY

摘要

A DC-DC converter for power supply is provided to amplify output through a blocking oscillator and control an output voltage of the blocking oscillator through a controller, thereby improving conversion efficiency of input voltage to output voltage. A DC-DC converter for power supply includes a blocking oscillator(100), a rectifying unit, a smoothing unit, and a blocking oscillator controller(200). The blocking oscillator is connected to commercial DC power(V1) to output boosted voltage. The rectifying unit rectifies the voltage outputted from the blocking oscillator to flow in one direction. The smoothing unit smooths the voltage outputted from the rectifying unit. The blocking oscillator controller is connected to the DC power and the blocking oscillator and controls the blocking oscillator to provide the stable output voltage.
