FAQ:

Q: How does a switching power supply adapter work?

A: What is a switching power supply adapter? A switching power supply takes an AC input, but rectifies and filters into DC first, is converted back into AC at some high switching frequency, steps down the voltage with a transformer, then is rectified and filtered into a DC output.

Q: How are the two modes of switching power supply different?

A: They differ in that the output of the error amplifier (error voltage) passes through a voltage pulse conversion unit before driving the power transistor. Switching power supplies have two main modes of operation: forward conversion and boost conversion.

Q: How is a switching power supply different from a linear power supply?

A: In a linear power supply, the power transistor is operating in a linear mode. The PWM switching power supply, unlike a linear power supply, allows the power transistor to flip between on and off states.

Q: How does PWM control a switching transistor?

A: But, after the power transistor is in the switching state, pulse width modulation (PWM) control technology has developed. It uses to control the switching converter to get PWM switching power supply. It characterizes 20kHz pulse frequency or pulse width modulation.
