Half-Wave Rectifier With Capacitor Filter. A half-wave rectifier successfully converts an AC source into a DC output, but the half-sine wave pulsations are often undesired. The most commonly used DC sources are steady-state, meaning that the goal of rectification is a flat line rather than a pulsed sine wave.
About Photovoltaic Energy StorageThe capacitor is a reactive component, used in analog electronic filters because the capacitor impedance is a function of frequency. The capacitor that affects a signal can be frequency-dependent. So this property is widely used in designing the filter.
