Abstract

PWM type switching power supply with high efficiency and energy saving features is very suitable for portable electronic devices, and has been widely used in the fields of communication, computer and other fields. The PWM control link in the switch power chip is the key and the core of the technology. The design of the PWM pulse control part is a combination of hardware and software program is established, the software programming of PWM pulse duty cycle adjustable through 89C51, MOSFET controlled by pulse tube breaking fixed value of DC can be input into DC adjustable.
