This paper presents a method of using selective harmonic elimination PWM (SHEPWM) as part of a control strategy for a multilevel rectifier. Such a power converter can be applied as part of a solid-state replacement for a distribution transformer. The paper discusses problems with DC link voltage balancing on the converter and how SHEPWM can be manipulated to solve these problems. The full DC link...
Iron losses due to flux harmonics in stator cores of pulse-width-modulation [PWM] back-to-back inverter-fed induction motors have a major effect on system efficiency. A new generation of direct AC-AC matrix converters offer important advantages over classical frequency converters such as absence of bulky and temperature sensitive DC-links and possible adjustment of power factor. The paper presents...
