| Abstract |
Electric power conversion system market is expanding as renewable energy industry rapidly grows. Most of these electric power conversion systems typically ranging from 10kW to 250kW, are controlled by high speed digital signal processor. This paper proposes a three phase inverter system each arm of which is equipped with DSP together with gate driver. In existing inverters, main DSP generates PWM signals and controls all three arms. In the proposed inverter, each arm is independently self-controlled by dedicated DSP that measures phase voltage/current and generates PWM signals, according to synchronization and control reference data sent by main DSP via serial communication ie. CAN communication. The proposed controller can be used for unballenced 3phase load. The experimental results are proposed for proving the control methode. |
