Power standard based on a high precision power-factor meter
(IEEE, 1998)
A high-precision power-factor meter, based on zero crossing detectors, is proposed. The influence of the distortion in the input signals is analyzed and low pass filters proposed to prevent this error source. This system ...
A new three-phase low THD power supply with high-frequency isolation and 60V/200A regulated DC output
(2001-10-22)
This work proposes a new isolated high power factor 12kW power supply based on an 18-pulse transformer arrangement. Three full-bridge converters are used for isolation and to balance the DC-link currents, without current ...
