Abstract :
A 100 kVA power conditioner for three-phase four wire emergency generators is presented to compensate current harmonics and asymmetries caused by nonlinear and/or unbalanced loads. Three-phase voltage type converter with split-dc-capacitor is adopted as the power circuit and a new direct source current control method is suggested, which simplifies the controller. The proposed power conditioner shapes the generator current sinusoidally inphase with the voltage and allows the generator to supply maximum power even to single phase loads. An IGBT based 100 kVA prototype with the controller realized with a DSP (TMS320C32) is built and tested to verify the performance of the power conditioner
