Hisense KFR-25GW-06BP inverter air conditioner indoor fan motor drive circuit

Shown is the Hisense KlrR25GW/06BP ​​variable frequency kiln regulator indoor fan motor drive circuit . As can be seen from the figure, the indoor fan
motor is powered by an AC 220 V power supply. The L end of the AC input circuit is connected to the common end of the motor through TLP361.
The live wire (N) of the AC 220 V input is added to the motor's running winding, and then The starting capacitor C is added to the starting winding of the motor. Only when the thyristor in TLP361
is turned on can voltage be added to the motor winding. The thyristor in TLP361 is controlled by the light-emitting diode. When the light-emitting diode
emits light, the thyristor turns on and current flows.
