The Type of Switching Power Supply is Based on the Modulation Method

Most switching power supply circuits use a feedback closed-loop loop composed of sampling circuits, coupling circuits, etc. to control the pulse width of the PWM (or SPWM) drive signal, and finally achieve the purpose of stabilizing the output voltage amplitude.

There are several classifications of switching power supply EMI transmission channels

The Main Reasons For The Low Output Voltage Caused By The Power Adapter

Output Overload Protection Methods For Switching Power Adapter

in order to ensure that the adapter can adapt to the operating requirements of different environments during use and can provide users with continuous and stable current-voltage conversion work, the adapter is usually provided with appropriate output overload protection to ensure the safe operation of the adapter
