Power and ElectricalDC Machine Maintenance and Power Electronics Fundamentals
Power electronics sits behind modern electrical and electromechanical systems, from utility networks and industrial drives through to transportation, renewable generation and infrastructure projects. This course builds a working understanding of power conversion using modern electronic switching devices, with direct application to DC machines and the converter interfaces around them. Delegates review the structure, characteristics and performance of ideal and practical switching devices, then examine the main converter topologies in detail: AC to DC rectifiers, DC to DC switching regulators and DC to AC inverters. Resonant and soft switching conversion are introduced alongside systematic methods for circuit analysis, including waveform evaluation and the calculation of average and RMS values, power, power factor and harmonic content. The programme is built around real case studies, guided exercises and hands on workshops.
