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. WebFlyback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。.
