• The switching power supply is different from the linear power supply. The switching transistors used in the switching power supply are mostly switched between the fully open mode (saturation area) and the fully closed mode (cutoff area). Both modes have the characteristics of low dissipation. 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 on and off time of the transistor. On the contrary, in the process of generating the output voltage of the linear power supply, the transistor works in the amplifying area and itself consumes power. The high conversion efficiency of the switching power supply is a major advantage, and because the switching power supply has a high operating frequency, a small size and light weight transformer can be used, so the switching power supply will also be smaller in size and lighter in weight than the linear power supply.
