Flyback transformer output voltage
The primary winding of the flyback transformer is driven by a switch from a DC supply (usually a transistor). When the switch is switched on, the primary inductance causes the current to build up in a ramp. An integral diode connected in series with the secondary winding prevents the formation of secondary current that would eventually oppose the primary current ramp. WebApr 8, 2024 · The flyback converter produces a regulated output with control over the magnitude of the input voltage. The flyback converter also allows the possibility of using pulse width modulation (PWM) in a continuous mode of operation, as shown in Figure 2.
