The relationship between the absorption power (peak value) of transient voltage and the pulse width of transient voltage is only given in the manual as the absorption power (peak value) at a specific pulse width. However, the pulse width in the actual circuit is unpredictable and needs to be estimated in advance. Wide pulses should be downgraded for use.

Static phase shifter is connected in series in the rotor circuit of a motor, which changes the phase relationship between the rotor current and rotor voltage, and then changes the phase relationship between the stator current and voltage of the motor, in order to improve the power factor and efficiency of the motor itself, increase the motor overload capacity, reduce the stator current of the motor, and reduce the motor's own losses.

During operation, no voltage is applied between the gate and source. Unlike enhanced MOS transistors, there is a conductive channel between the drain and source. Therefore, as long as a forward voltage is applied between the drain and source, a drain current will be generated.

When there is no voltage applied between the gate and source during operation, the PN junction between the drain and source is reversed, so there is no conductive channel. Even if a voltage is applied between the drain and source, the conductive channel is closed and no current flows through.

When conducting, the driving circuit should be able to provide sufficient charging current to quickly raise the voltage between the MOSFET gate and source to the required value, ensuring that the switch tube can be quickly turned on and there is no high-frequency oscillation of the rising edge.
