By using some common approaches and modifications are needed in inverter configuration for multiple-load application. This paper presents an inverter configuration with two loads by using pulse density modulation control technique. It allows the output power control of each load independently with constant switching frequency and constant duty-ratio. The pulse density modulation control technique is obtained using phase on-off control between two legs of the inverter to reduce acoustic noise. The proposed configuration provides reducing the component count for extension of multiple-loads. The control technique provides wide range of output power control. In addition, it can achieve efficient and stable ZVS operation in the whole load range. The proposed configuration and control scheme is simulated and experimentally verified.

The details on the construction of sub models for the induction motor are given and their implementation in SIMULINK delineated. The required equations are stated at the beginning and then a d-q model of induction motor is developed. This plan could be led to other engineering systems.
