Fig. 1 shows an inductor connected to a battery - a constant voltage source. The resistor represents the small residual resistance of the inductor's wire windings. When the switch is closed, the voltage from the battery is applied to the inductor, causing current from the battery's positive terminal to flow down through the inductor and resistor. The increase in current causes a back EMF (… WebA flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer.

WebSep 5, 2024 · These variations of the flyback converter use nondissipative clamping techniques to recycle leakage energy and improve efficiency. In the standard form of a flyback converter, the leakage inductance of the transformer creates a voltage spike on the drain of the primary field-effect transistor (FET). WebThe flyback voltage couples across the mutual inductance, Lm, but not the primary leakage inductance. When switch Q1 turns off, the current in both inductances will continue to flow somewhere. Mutual inductance current will divert to the secondary and flow through the Vfbsource, with current decreasing at the rate of –Vfb/Lm.
