Microchip Controlling High Frequency Adjustable Three Phase Inverter

The paper deals with implementation and designing of Step Sinus Pulse Width Modulation (SSPWM) method for inverter controlling of three- phase asynchronous machine R (resistive)and L (inductive) loads. After new pulse width modulation method presented in the paper the new mathematical model of three-phase inverter is developed for one and three-phase loads. So mathematical models are calculated for SSPWM driving induction machine and three phase R and L loads while switches on inverter are operated by SSPWM. Then Direct Current (DC)/Alternating Current (AC) inverter can be constructed for high performance inverter. Firstly three-phase induction machine is simulated at the Matlab Simulink after models are described in section a b and c. Rotor and stator current electromagnetic torque rotor speed harmonic distortions are given in section d according to the simulation results. Secondly; R L loads and three phase induction machine are implemented with real circuit elements.
