Flyback clamp
WebNov 18, 2024 · Many brushed DC motor designs include a flyback diode by default. I typically see Schottky diodes recommended. That would allow current to circulate similar to connecting the terminals, and would clamp the motor voltage to ~300mV or less (and also in the same direction as the back EMF.)

It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters.
WebA novel dual-mode control scheme is proposed in this paper that permits the active-clamp flyback (ACF) converter to operate in both the quasi-resonant (QR) mode under light load and the... WebDec 16, 2024 · Usually flyback diodes are used directly across the inductive load (and not the MOSFET) to prevent voltage spikes if the transistor is turned off. Thanks to the overvoltage protection diodes the MOSFET should be safe, but other parts may not. Should I use these protected MOSFETs without a flyback diode and what pitfalls may occur? …
Webachieving high efficiency. The Active Clamp Flyback (ACF) operation simplifies EMI filter design to avoid interference with other sensitive circuits in the system. The NCP1568 … WebJun 19, 1994 · Incorporation of active-clamp circuitry into the flyback topology serves to recycle transformer leakage energy while minimizing switch voltage stress. The addition of the active-clamp circuit also provides a mechanism for achieving zero-voltage-switching (ZVS) of both the primary and auxiliary switches.
