When the FET switches off, this energy is dumped into the secondary, allowing current to flow in the secondary, so the primary current collapses immediately to zero. bridges school north mankato mnWebJun 9, 2024 · Hi everyone. I am tryig to obtain the gain and frequency plots of a flyback converter controlled with LT8316. LTspice does not provide any frequency response feature but I use middlebrook's method to obtain frequency response. However, result is too weird. I simply insert a small ac signal thru the FB loop of the controller and sweep that source. bridges self management principles
