To protect the microcontroller and optimize control, it is common to use an inverter to isolate the microcontroller and the controlled element. The inverter can not invert the signal but also boost the control signal amplitude to better drive the subsequent MOSFET
In general, the "fly diode" in a circuit is used to protect components from being punctured or burned out by induced voltage.
In the design of power switching circuits, we should first focus on the that commonly used simple power switching circuits have.
Some partners have privately messaged to write an article about the transformer-isolated MOSFET drive circuit. Today, the YFW editor will talk about the principle of the transformer-isolated MOS drive circuit.
In an ideal state when MOSFETs, the MOSFET gate drive waveform is a relatively smooth pulse signal, Ideal square wave
The drain-source current and the resistance are the key indicators for determining the load capacity of MOSFETs.
