The working principle and application of bridge rectifier KBPC5010:
The purpose of bridge rectifier KBPC5010 is to convert alternating current into direct current. What is the working principle of the bridge rectifier in the circuit?
The rectification in the bridge rectifier is a term. It completes its work through the principle of unidirectional conduction of the diode. To put it simply, the diode is unidirectional, which is forward conduction and reverse cutoff. In other words, the diode only allows its positive pole to enter positive electricity and its negative pole to enter negative electricity. The diode only allows current to pass in one direction, so when it is connected to an AC circuit, it can make the current in the circuit flow only in one direction, the so-called "rectification". Among them, two diodes are half-wave bridge rectifiers, and four are full-wave bridge rectifiers.
1. Rectifier circuit: use a bridge rectifier with unidirectional conductivity, which can also be called a bridge rectifier stack. Convert the 50HZ alternating current in the circuit whose direction and size are changed into direct current with the same direction but still pulsating in size.
2. Filter circuit: Utilizing the nature of the energy storage element that the voltage at both ends of the capacitor C cannot change suddenly, connecting the capacitor C in parallel with the load RL of the rectifier circuit can filter out most of the AC components in the output of the rectifier circuit, thereby obtaining a relatively smooth Direct current. In low-power rectifier circuits, capacitor filtering is often used.
3. Power transformer: transform the AC voltage of the grid into an AC voltage that meets the requirements, and the AC voltage can be rectified to obtain the DC voltage required by the electronic equipment.
4. Voltage stabilizer circuit: When the grid voltage or load current changes, the amplitude of the DC voltage output by the filter circuit will also change accordingly. Therefore, the function of the stabilizer circuit is to stabilize the DC voltage after rectification and filtering. In the low-power DC power supply, several common rectifier bridge circuits are single-phase half-wave, full-wave, bridge and three-phase, among which there are both AC and DC.
By using a secondary winding of the transformer and the rectifier bridge, the load of the rectifier circuit can have pulsating DC voltage and current in the same direction within the positive and negative half cycles of the AC power supply.
