There are many power adapters that we often see and use in our lives. But rarely understand what is the difference between power adapters. In fact, the difference between power adapters is quite big, each one has a specific use, must a certain piece of electronic equipment on. Improper use of lightly damaged equipment, or cause safety accidents. Next to share with you what are the classifications of power adapters!


Classification by modulation mode


1. pulse-width modulation type switching power adapter. Oscillation frequency remains unchanged, by changing the pulse width to change and adjust the size of the output voltage, sometimes through the sampling circuit, coupling circuit, etc. to form a feedback closed-loop circuit to stabilize the amplitude of the output voltage.

2. Frequency modulation type switching power adapter. Duty cycle is kept constant, and the amplitude of the output voltage is adjusted and stabilized by changing the oscillation frequency of the oscillator.

3. Hybrid modulated switching power adapter. By adjusting the on-time oscillation frequency to complete the adjustment and stabilization of the output voltage amplitude.




Classification by excitation mode


1. His excitation type switching power adapter. The circuit is equipped with an oscillator to excite the signal.

2. Self-excited switching power adapter. Switching tube doubles as an oscillator in the oscillator tube.


Classification by circuit structure


1. Bulk switching power adapter. The entire switching regulator power adapter circuit is composed of discrete components, its structure is more complex and less reliable.

2. Integrated circuit type switching regulator power adapter. The entire switching power adapter circuit or a part of the circuit is composed of integrated circuits, such integrated circuits are usually thick film circuits. Some thick film integrated circuits include switching tubes, and some do not include switching tubes. This type of switching power adapter is characterized by simple circuit structure, easy debugging, and high reliability.
