DC power supply is generally composed of several parts

DC power supply is generally composed of several parts

Answer:

DC power supply is mainly composed of four parts: power transformers, rectifier circuit, filter circuit and voltage regulator circuit.

1. Power Transformers: The AC voltage into the rectifier circuit required AC voltage, the general secondary voltage u2 smaller. 2. Rectifier circuit: The transformer secondary AC voltage u2 into a one-way DC voltage u3, which contains the DC component and many harmonic components. 3. Filter circuit: Filter out the ripple voltage u3 harmonic components, the output more smooth DC voltage u4. The voltage is often changed with the grid voltage and load current changes. 4. Regulator circuit:

It can be in the grid voltage and load current changes, to maintain the output DC voltage stability. It is an important part of DC power supply, DC power supply determines the important performance indicators.
