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 modulated 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.Keywords:
