A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power … See more 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 … See more When used with a DC coil relay, a flyback diode can cause delayed drop-out of the contacts when power is removed, due to the continued circulation of current in the relay coil and diode.

The current flowing during the on time is usually referred to as magnetizing current, whereas the current flowing during the off time is called the flyback current. The energy stored in the inductor during the on time is used to drive the flyback current [5]. Figure 2. shenley term datesWebFlyback topologies are practical and lowest cost for systems up to power levels of 100W. Above this power level other methods such as forward converters become more cost effective, due to reduced voltage and current stresses on the devices. Flyback transformer design is a somewhat iterative process, due to the number of variables involved, but it spotted bass habitat
