Abstract：

Switch　mode　power　supply　is　a　good　selection　for　UAV.　The　forward　converter　will　generate　transient　voltage　spikes　when　the　power　is　switched　off　and　cause　wide-band　electromagnetic　interference　with　a　continuous　spectrum.　The　higher　level　of　the　resonant　reset　will　destroy　the　metal-oxide-semicondutor　field-effect　transistor　(MOSFET).　This　paper　analyzes　the　magnetic　field　of　the　forward　converter　transformer,　explains　the　reasons　in　forming　voltage　spike　of　the　MOSFET,　designs　a　RC　branch　in　parallel　to　the　magnet,　and　presents　a　way　to　select　the　parameters　of　the　component.　To　guarantee　the　long-term　operation　of　the　switch,　the　resistor,　capacitor,　and　diode　(RCD)　resonant　reset　circuit　is　designed.　The　experimental　results　agree　well　with　the　analysis　conclusions.
