What are the working modes of the switching power supply?

Issue Time:2019-05-14
Switching power supply is everywhere, and it is an indispensable electrical product. The switching power supply is composed of both MOSFET and pulse width modulation. It uses electronic technology to control the switching power supply's turn-on and turn-off time. Then what are the working modes of the switching power supply? Here are the Shenzhen Lianyun Da Xiaobian to bring you to understand.

Switching power supplies generally have three modes of operation:

1. Frequency and pulse width fixed mode, mostly used for DC/AC inverter power supply.

2, fixed frequency, variable pulse width mode, mostly used for switching power supply.

3, frequency, pulse width variable mode, mostly used for switching power supply.

The switching power supply works by operating the power transistor in a linear mode in a linear power supply. The PWM switching power supply is a state in which the power transistor is turned on and off. In these two states, the semiconductor applied to the power transistor. The losses generated on the device are small.

Shenzhen Lianyunda Electronics Co., Ltd. is a professional manufacturer of switching power supplies, producing high quality switching power supplies, power adapters, medical power supplies, LED power supplies and other power products.
