Detailed Power Loss Analysis of T-Type Neutral Point Clamped Converter for Reactive Power Compensation

The paper presents an analysis of power losses in a three-phase T-type neutral point clamped converter with insulated gate bipolar transistors. paper’s main aim is to perform detailed the operating as active filter. study based on use characteristics semiconductor devices provided by manufacturer module datasheet. Thanks analysis, it possible recognise value losses, which facilitates design cooling system. Identifying how are distributed between switching also possible. Power shown functions output current and temperature. results were successfully verified measuring using laboratory model rated currents 10 20 A. obtained indicate relatively low even distribution devices. This superior feature three-level topology.
