The circuit can be used to adjust the speed of the ShenLI electromotor or the single-phase asynchronous motor, it is the half-wave controlled rectifier circuit. When there is no load, the armature has high EMF, so that at the end of the half cycle, the thyristor is triggered immediately. When there is load, the armature's voltage reduces, the thyristor will be triggered in the rising voltage part. The L1, L2 and the capacitances C4 and C5 can be used to resist the interference.
