4.2. Power Components Calculation and Power Quality for Nonlinear Loads
4.2.1. Power Components Calculation for Sinusoidal Voltage and Nonsinusoidal Input Current
A nonlinear load connected to the utility grid is a load that apart from its linear or passive elements (inductors, resistors, capacitors) includes also nonlinear elements, such as power semiconductor devices (e.g., diodes, thyristors, metal oxide semiconductor field effect transistors, insulated gate bipolar transistors, etc.). For example, a diode rectifier with R–L load is considered to be a nonlinear load to the power utility grid because of the presence of diodes, which are nonlinear elements. When the rectifier input voltage is a sinusoidal waveform and the input current a nonsinusoidal ...
