This article will explain in detail the use of reverse converter Buck-Boost for you. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Characteristics

For step-up and step-down choppers, the polarity of input and output is opposite, and the inductor transmits energy.

Working process

When the MOS is turned on, the input power supply charges the inductor L; when the MOS is disconnected, the inductor discharges the load to realize the power transmission. So, the L here is used to transmit energy.

Input-output relationship

Duty cycle D=T_on/ (T_on+T_off)

Period T = T_on + T_off

The principle of volt-second balance on the same magnetic core

V_in*T_on+V_out*T_off=0

Get:

Vroomout =-V_in * (T_on/T_off) =-V_in * T * D / (1MZ D) (valid for continuous mode only)

The intermittent mode T_off also subtracts the dead zone.

This is the end of the article on "what is the use of reverse converter Buck-Boost". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
