Tips: Difference between linear power supply and switching power supply

The power regulating tube of the linear power supply always works in the amplification area, and the current flowing through it is continuous. Due to the large power loss on the adjustment tube, a larger power adjustment tube is required and a large radiator is installed. The heat generation is serious and the efficiency is very low.

The working mode of the linear power supply makes it necessary to have a voltage device to change from high voltage to low voltage. Generally, it is a transformer, and there are others, and then output DC voltage through rectification. In this way, the volume is large, relatively bulky, low efficiency, and large heat generation; but it also has advantages: small ripple, good adjustment rate, small external interference, suitable for use with analog circuits/various amplifiers, etc.

The power device of the switching power supply works in the switching state, and the energy is temporarily stored through the inductive coil when the voltage is adjusted, so that its loss is small, the efficiency is high, and the requirements for heat dissipation are low, but it has a high demand for transformers and energy storage inductors. There are also higher requirements, which should be made of materials with low loss and high magnetic permeability. Its transformer is a small word. The total efficiency is 80% to 98%. The efficiency of the switching power supply is high but the volume is small, but compared with the linear power supply, the voltage and current regulation rate has a certain discount.
