Abstract :
This paper presents the steady state analysis of a three-phase switched boost inverter (SBI). A Pulse Width Modulation (PWM) control strategy suitable for the gate control signal generation of the three-phase SBI is also described in this paper. The proposed PWM control technique has been implemented in digital domain using Texas Instruments TMS320F28335 digital signal processor (DSP). The steady state analysis and the PWM control technique are verified using an experimental prototype of three-phase SBI supplying a balanced three-phase load. The gate control signals for the experimental prototype of SBI are generated using the DSP. A comparison of the SBI with traditional three-phase voltage source inverter (VSI) for the same input and control parameters is also given in this paper. The experimental results presented in the paper show good correlation with the theoretical analysis.
