Input filter design for current source PWM GTO converter

0

TL;DRAbstract

The authors describe the current harmonics which occur in the input/output terminals of a CS PWM GTO power converter. First, two kinds of switching methods are analyzed by comparison. Second, a novel type of LC filter configuration named as LRC filter, is proposed and analyzed. A simple design method and design data for the proposed filter configuration are presented and compared with the serial damping resistor type. The steady state and dynamic performances of the system are investigated. Simulation and experimental results are also presented in the paper.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
