C1, C2 filter out ripples and spikes, and TVS1 stabilizes to prevent excessive output voltage.

The middle one is the rectifier stack.

The front is overcurrent protection and overvoltage protection, C1, C2 filtering, TVS1 voltage stabilization.

Fuse + NTC protection circuit prevents abnormal current and temperature, C1 smooth waveform takes into account low frequency C2 takes into account high frequency TVS1 voltage stabilization protection RL similar load.
