12v Ac 1000ma Power Adapter
Switching power supply is to use the circuit to control the switch tube for high-speed channel and cut-off. The DC power is converted into high-frequency AC power and supplied to the transformer for voltage transformation, so as to produce the required group or groups of voltage
Description
Description
AC power charger The AC power input is rectified and filtered to DC;The switch tube is controlled by high frequency PWM (pulse width modulation) signal to add the DC to the primary of the switch transformer;
High frequency voltage is induced from the secondary of the switch transformer and supplied to the load through rectification and filtering;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
