WebJan 5, 2012 · So a 25 amp motor will store 12.5 amps. Since the diode will see the same current during fly-back it will see 12.5 amps but only for 50% of the time or 6.25 amps average. Higher duty cycle will produce diode peak currents up to 25 amps but for only a very short part of the PWM cycle. WebFreewheeling Diode in Controlled Rectifier. In motor control circuits, a diode known as the freewheeling diode is connected across motor terminals to allow for dissipation of energy stored in motor inductance and to provide for continuity of motor current when the SCRs are blocked. It also provides protection against transient over voltages. エヴァ 鼻 https://energybyedison.com
