10W-500W Switching Power Supply
After the AC voltage is rectified and filtered by the rectifier circuit and the filter circuit, it becomes a DC voltage with a certain pulsating component. The voltage enters the high-frequency converter and is converted into a square wave of the required voltage value. Finally, the square wave voltage is rectified and filtered. to the required DC voltage. The control circuit is a pulse width modulator, which is mainly composed of a sampler, a comparator, an oscillator, a pulse width modulation and a reference voltage circuit. This part of the circuit has been integrated at present, and various integrated circuits for switching power supplies have been made. The control circuit is used to adjust the switching time ratio of the high frequency switching element to achieve the purpose of stabilizing the output voltage.
