Abstract :
Modulation strategy for a matrix structured ac to dc converter is developed. This modulation strategy enables the input displacement factor correction without current sensing. Mathematical proof that the ac to dc converter can operate with unity input displacement factor is provided by analysis based on the switching matrix approach. Theoretical analysis demonstrates the algorithm requirements. Computer simulation and experimental results supporting this ability are reported
