Although the induction generator in the Fig. 5 (a) is three phases generator that uses three capacitors,
but for single phase generator is just used only a capacitor that connected across the two wires of generator.
In addition to the single phase induction machines in the market have almost two winding, such as split
phase motor, capacitor motor, and the parameter of the two windings are not the same. So, it may be have
the problem to the system from unequal voltage of two winding.
