Evaluate design metrics 1. Input parameters: input voltage size, AC or DC, number of phases, frequency, etc. International voltage levels include single-phase 120Vac, 220Vac, 230Vac, etc. The internationally accepted AC voltage range is 85~265V. Generally includes the input voltage rating…

1: What is a linear series regulated power supply? Answer: Linear regulated power supply means that the adjusting power tube in the regulated power supply circuit works in the linear amplification area; series switching regulated power supply circuit means that…

What is the power supply? A power supply is an electrical device that converts current from an energy source (such as a power grid) into the voltage required by a load (such as a motor or electronic device). There are…

Switching power supply should be commonly used in electronic equipment. The full English name is Switch Mode Power Supply, or SMPS for short. It is also called switching power supply and switching converter. It is a high-frequency conversion device. The…

A switching power supply is a power supply that uses modern power electronics technology to control the turn-on and turn-off time ratio of the switch tube to maintain a stable output voltage. The switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET.

The most basic topologies are Buck (buck), Boost (boost) and Buck/Boost (boost/buck), single-ended flyback (isolated flyback), forward, push-pull, half-bridge and full-bridge.

There are two types of modern switching power supplies: one is DC switching power supply; the other is AC switching power supply.
