Function of power switch
The power switch is to use the circuit to control the switch tube for high-speed channel connection and cut-off. The direct current is transformed into high-frequency alternating current and supplied to the transformer for voltage transformation, so as to produce one or more groups of voltages required!
1. AC power input is rectified and filtered into DC; 2. The switch tube is controlled by high-frequency PWM (pulse width modulation) signal, and the DC is added to the primary of the switching transformer; 3. High frequency voltage is induced from the secondary of the switching transformer and supplied to the load through rectification and filtering; 4. The output part is fed back to the control circuit through a certain circuit to control the PWM duty cycle, so as to achieve the purpose of stable output.
