WebSep 8, 2024 · A flyback diode is placed with reverse polarity from the power supply and in parallel to the relay’s inductance coil. The use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. They are sometimes called flywheel diodes, freewheeling diodes, relay diodes, or snubber diodes. Web下文介绍三种flyback电路的作用。 电路一 此开关电源属于自激式开关电源,三极管13003为电源开关管,C945为过流保护三极管管,10欧电阻为过流取样电阻,二极管4148这里作为0.7V稳压二极管使用,作为过流保护的 …

WebThe duty cycle of flyback transformers typically does not exceed 0.5. Various combinations of turns ratios and duty cycles can be used to achieve the required output voltage according to this equation: V out = V in * (N s … 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. how to sit when pregnant
