http://boginjr.com/electronics/hv/flyback-driver-2/ WebA flyback transformer is a coupled inductor with a gapped core. During each cycle, when the input voltage is applied to the primary winding, energy is stored in the gap of the core. It is then transferred to the secondary …
WebNov 7, 2024 · There are basically 2 kinds of modern flybacks, television flybacks are driven near 15kHz and monitor flybacks are driven between 30-150Khz. Depending on which type we use, we have to adjust the … WebDefinition: A flyback transformer can be defined as an energy conversion device that transfers energy from one part of the circuit to the other part at constant power. In a flyback transformer, the voltage is stepped up to a very high value based on the application.

WebAn NE555 is a poor choice for driving a MOSFET (even logic-level) as it cannot sink and source much current. Put a monolithic MOSFET driver IC between the 555 and the MOSFET and your power dissipation will improve. Does MOSFET overheat due to undervoltage on gate (hence not fully opened) or cracked transformer core?
