WebDec 28, 2024 · flyback电路的作用详解-Flyback变换器，俗称单端反激式DC－DC变换器，又称为返驰式（Flyback）转换器，或“Buck-Boost”转换器，因其输出端在原边绕组断开电源时获得能量，因此得名。 Webfeetwet. 2,322 9 30 55. 2. "Flyback" is a play on words, the same as "bootstrap" is for amplifiers and software. It is a way of feeding some of the output back to an input stage to boost performance. The term originated in the 1950's with the HV flyback transformer for the picture tube. soiled notes rbi circular
