    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.

    Existing reviews of 15V DC 3A 100W Switching Power Supply
    So cheap.
    I replaced the burned out power converter in my RV with this new witching power supply. It’s been working great for months with no issues. I’m going to buy another one for back up since we use it every day and it’s so cheap.
