In my projects when I need to convert AC to DC, I use already made rectifiers like the HLK-10M05 module. There are some disadvantages that come with using the module as a stand alone, the biggest being just that; it is too big.
As an alternative, you can build a rectifier circuit into your project. The circuit works to convert AC to specified DC power.
The components you require to make the circuit are:
- 4 diodes whose connection converts the DC to AC without changing the voltage
- 1 Zener diode to drop down the voltage
- a smoothening capacitor to smoothen out the irregular DC voltage
- two resistors to trim the voltage output to get the exact voltage and current you need. When selecting these resistance, your target should be high current low resistance.
With just 4 components, you make a AC-DC converter that takes up about 20mm of space. I will later update the circuit for my rectifier with an update on its functionality on my project.
