Rectifier transformer is typical ac-dc converter for improving power quality by reducing the harmonic in ac mains and ripples in dc output. The design of rectifier transformer is difficult because it originates from the experience of designers. So a designer who is lack of experience would result in a waste of material and cost. In order to reduce the manufacturing cost of rectifier transformer, this...
Phase-shifting reactor (PSR) can be used to solve the harmonic problems caused by rectifiers. In this paper, according to the active power balance principle, the relationships among the DC current of the loads, the currents of power supply side, and the capacity of core limb are built, the product specification of winding and core are obtained. Meanwhile, the coupled field-circuit method based on...
