Bipolar DC power supply experimental preparation

     Bipolar DC power supply related knowledge

 

     Through the design, installation and commissioning of integrated DC regulated power supplies, it is required to learn:

     (1) Selecting a transformer, a rectifier diode, a filter capacitor, and an integrated voltage regulator to design a DC regulated power supply;

     (2) Master the debugging of DC voltage regulator circuit and the test method of main technical indicators.

 

     Bipolar DC power supply design task

 

     Design a waveform DC regulated power supply to meet:

     (1) When the input voltage is 220V±10%, the output voltage is adjustable from 3-12V, and the output current is greater than 1A;

     (2) The output ripple voltage is less than 5mV, the voltage regulation coefficient is less than 5×10-3, and the output internal resistance is less than 0.1 ohm.
