| Abstract |
The application of Pulse Density Modulation (PDM) control to a rectifier - series resonant
inverter set makes it possible to implement an ac/ac converter with good performances (size and
efficiency). However its power factor decreases when the load power decreases. We propose a PDM
control strategy adapted to a set of identical ac/ac converters, to obtain mutual compensation of the
harmonic distortion among the ac/ac converters. The set presents a power factor close to 1 for power
levels ranging between 100/G % and 100 % of the full power, where G is the number of ac/ac converters
in the system. |
