Switching power supplies are different from linear power supplies. Most of the switching transistors used in switching power supplies are switched between fully-on mode (saturation zone) and fully-closed mode (cut-off zone). Both modes have low dissipation characteristics and switch between The conversion will have higher dissipation, but the time is very short, so it saves energy and generates less waste heat. Ideally, the switching power supply itself does not consume power. Voltage regulation is achieved by adjusting the time when the transistor is turned on and off. On the contrary, in the process of linear power supply generating output voltage, the transistor works in the amplifying area, and it also consumes power. The high conversion efficiency of the switching power supply is one of its advantages, and because the switching power supply has a high operating frequency, a small-sized and light-weight transformer can be used, so the switching power supply will be smaller in size and lighter than the linear power supply.
