ABSTRACT
A Delta Modulated, Buck Type, Three Phase PWM Converter was constructed and tested. The converter is of the current source type and can be used in conjunction with current source inverters. The d.c. current is regulated by proportional feedback control loop. By delta modulation of the voltages across the a.c. terminaIs of the converter, the a.c. source currents are "indirectly" controlled so that the fundamental components remain in a predefined phase with respect to the source voltages. Test results have shown that the converter draws near sinusoidal a.c. currents at unit y power factor, with leading power factor a possibility.
