The paper is dealing with two commonly used topologies for pulse width modulated inverters. The first is based on a PWM converter that transforms the DC-input voltage into a high DC-output voltage, followed by a PWM bridge for waveshaping and inversion. The second uses a forward PWM-converter for transformation and waveshaping at the same time. It is(More)
Phase controlled systems (PCS) built with nonlinear inductor filters for radio frequency interference (RFI) suppression give irregularites in the radio noise spectrum. These irregularities are important for the measurement of the RFI behavior of the PCS and the design of RFI filters. A theory is given that explains the most important observed effects. It is(More)
This paper discusses a realisation of a modular pulse width modulation (PWM) inverter with MOSFET-transistors, designed for UPS-applications. Each module contains a 500 Watt double-forward converter, equipped with a feedback circuit to minimize output distortion. Attention will be paid to the consequences of paralleling several modules: the load current has(More)
