Does SMPS use PWM?
The high frequency switching transformer that is used in SMPS is smaller and lighter than the transformer that is used in linear power supply. The on and off of the switch is controlled by PWM that generated by PIC microcontroller 16F877A.
Do power supplies use PWM?
The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations. In all cases, the PWM logic signal drives the switching power transistor, and the power transistor drives the load.
What is the function of PWM oscillator in SMPS?
SMPS rely on PWM to control the average value of the output voltage. The average value of the repetitive pulse waveform depends on the area under the waveform. As load increases, output voltage tends to fall. Most switching power supplies regulate their output using the method called Pulse – Width Modulation (PWM).
