| Abstract |
A three phase voltage controller has been designed to save energy when the motor is lightly loaded. In this paper power-factor maximisation concept and the stator current minimisation technique have been used together to make the controller a hybrid between current minimisation and power factor maximisation schemes. This has been implemented in two different ways: (i) Repeating the optimisation of the stator current until the motor side power factor reaches a reasonably good value like 0.8 (lag); (ii) Adopting a P-I controller algorithm first to bring the power factor angle to a preset reference value and then minimise the stator current. The results obtained by these two approaches are discussed here. |
