1. Input Grid Filter: Eliminates interference from the power grid, such as the startup of motors, switching of electrical appliances, lightning strikes, etc., and also prevents the high-frequency noise generated by switching power supplies from spreading into the grid. 2. Input Rectifier Filter: Converts the input voltage from the power grid into rectified and filtered voltage, providing direct current voltage for the converter. 3. Inverter: A critical component of switching power supplies. It converts direct current voltage into high-frequency alternating current voltage and serves to isolate the output section from the input power grid. Avionics Power Supply
4. Output Rectifier Filter: Converts the high-frequency AC voltage from the converter into the required DC voltage, while also preventing high-frequency noise from interfering with the load. 5. Control Circuit: Monitors the output DC voltage and compares it with a reference voltage, then amplifies it. Modulates the pulse width of the oscillator to control the converter, maintaining the stability of the output voltage. 6. Protection Circuit: In the event of overvoltage, overcurrent, or short-circuit in the switching power supply, the protection circuit stops the operation of the switching power supply to protect the load and the power supply itself. 36V Aviation Power Supply
