Estimation of Peak Voltage Value and its Occurrence Timing upon Non-Sinusoidal Supply Voltage

This paper presents a base for analytical expression development related to physical operation of the components in rectifier circuits. The relations are to be employed for explaining the dependency of harmonic load current on the harmonics of the supply voltage waveform. This study offers insights into the typical behaviour of circuits featuring single phase power electronic AC/DC converters, for example, LED lamps. By considering harmonic phase angle coupling, the assumptions presented can further be used to construct more effective and accurate models for load harmonic currents characterization. Proposed calculation approach defines the peak voltage values present for the bulk capacitor used along with rectifier, also peak timing respective to the main harmonic waveform presentation.
