Webb14 mars 2024 · Thus only some of the back emf inductor energy is lost and most is recycled. In the lone inductor circuit, to achieve the same result as with the dual mosfet circuit you'd have to find a way to get the back emf energy back into the power source. WebbFor ST7MC, it is possible to detect the back EMF during PWM on time. At high speed opera-tion (high duty cycle), the controller can detect the back EMF at the end of PWM on time. In this way, the controller avoids the resonant transition time. At low speed operation (low duty cycle), the controller can detect the back EMF at the end of PWM off ...
