We need to convert 220V, 50Hz alternating current into direct current. The whole process is divided into two parts: rectification and filtering. This part of the circuit is relatively simple. In this design, the rectifier bridge is used for rectification, and then the capacitor is used to filter it. The rectifier circuit can convert the input AC input voltage of a sinusoidal waveform into a DC voltage with a similar waveform. We usually use diodes to form a rectifier bridge to rectify the voltage. In this design, a full-bridge rectifier is used, and the finished rectifier bridge is used to form a circuit. The input sine wave signal makes the diodes of the rectifier bridge conduct alternately two by two to obtain a unidirectional pulse voltage containing harmonic components. <br>When selecting the rectifier bridge, the parameters of the reverse breakdown voltage should be considered.
