What are the classifications of power adapters?
2023-01
1. Classified by modulation mode
① Pulse width modulated switching power supply adapter. The oscillation frequency remains unchanged, and the output voltage is changed and adjusted by changing the pulse width. Sometimes the amplitude of the output voltage is stabilized by forming a feedback closed-loop loop through sampling circuit, coupling circuit, etc.
② Frequency modulation switching regulated power adapter. The duty cycle remains unchanged, and the amplitude of output voltage is adjusted and stabilized by changing the oscillation frequency of the oscillator.
③ Hybrid modulation switching regulated power adapter. Adjust and stabilize the amplitude of output voltage by adjusting the oscillation frequency of the on-time.
Integrated circuit type switching regulated power adapter. The whole switching power supply adapter circuit or part of the circuit is composed of integrated circuits, which are usually thick film circuits. Some thick film integrated circuits include switch tubes, while others do not. The switch power adapter is characterized by simple circuit structure, convenient debugging and high reliability.
