Modern photovoltaic (PV) installations are being installed in large numbers. Manufacturers are using different harmonized standards to show compliance with the legislative requirements such as the European EMC Directive. Their selection of harmonized standards is not based on adherence to (essential requirements of) the European EMC Directive, but more on what is most convenient, i.e. lowest cost;...
Modern so-called energy efficient equipment often draw current only during a very short period of the period of a power supply mains. This is causing unwanted non-sinusoidal and harmonic currents. In some cases even a single diode is used for rectification causing direct current (DC) in the mains supply. To reduce dissipation the semiconductor components switch very fast, which is causing interference,...
