Control of Three-to-Five-Phase Matrix Converter Using Carrier-Based PWM Algorithm
- This paper proposes a simple Carrier-Based PWM (CBPWM) technique to control the three- to five-phase Direct Matrix Converter (3×5 DMC). The proposed technique uses the indirect modulation approach to control the 3×5 DMC such as a three-phase ...
