5.Pwmic (Integrated Circuit): Using a certain process, the transistors, resistors, capacitors, inductors and other components required in the circuit are interconnected, placed on one or more small semiconductor chips or media substrates, and then encapsulated in a tube case to form a microstructure with the desired circuit function;


6. Switch Transformer: DC input voltage is regarded as a DC pulse voltage sequence, that is, a single-polar pulse voltage, which is supplied directly to the switch transformer by the on-off function of the control switch.


7. Electrolytic capacitor: The electrolytic capacitor is named for the use of electrolytes as electrodes (negative). One end of the electrolytic capacitor is positive and the other end is negative and cannot be reversed. Positive terminals are connected to the positive extremes of the rectifier output circuit, and negative extremes are connected to the negative extremes of the circuit. In all circuits that require AC-DC conversion, setting the filter capacitor not only makes the electronic circuit more stable, but also reduces the interference of the alternating pulsation ripple to the electronic circuit


8. Power adapter high-power switch tube: is one of the core components of switching power supply. Switch power supply can be "off" operation, switch tube power supply is essential.
