Advantage 1: Simple summary: low power consumption, high efficiency, small and light
Its biggest advantage is that it is more efficient. The reason is that in the switching state, the power consumption of the transistor itself is small, and it can reach 70% to 80% efficiency. At the same time, it does not need a step-down transformer. Its output transformer works at high frequency, and its volume is less than 50 Hz power frequency. transformer. Therefore, the circuit of the switching regulated power supply has the advantages of small size and light weight. It can work normally in a wide voltage range.
Advantage 2: Wide voltage regulation range
The output voltage from the switching regulated power supply is regulated by the duty cycle of the excitation signal, and the change of the input signal voltage can be compensated by frequency modulation or width modulation. Can guarantee a relatively stable output voltage. In general, the voltage regulation range of the switching power supply is very wide, and the voltage regulation effect is relatively good.
Advantage 3: The circuit form is flexible and diverse
For example, there are self-excited and other-excited types, width-modulated and frequency-modulated types, single-ended and double-ended, etc. Power supply developers can take advantage of various types of circuits to design and develop products that can meet different application environments. switching regulated power supply.
