Speed Control of Single Phase Induction Motor using Triac (Fan Regulator): The conventional speed regulator for a fan uses a resistance regulator. The regulator resistance is in series with the fan motor. The speed of the fan is reduced, whenever desired, by increasing the regulator resistance.

There are two key differences in the converter connection points. First, the series capacitor is inserted between the high side and low side switch of phase A. Second, the drain of the phase B high side switch is connected to the source of the phase A high side switch instead of the input supply.
The series capacitor acts as an input capacitor to phase B and brings the phase B switch node up to approximately half the input voltage as shown in Figure 10. It is discharged a small amount by the phase B inductor current which rises during this interval as shown in Figure 8.
