The paper presents a study of a power electronics device, based on a series resonant circuit with a parallel loaded capacitor. Two circuits are reviewed in consideration: a Buck DC-DC converter and a resonant parallel-loaded inverter. The difference between the two circuits is only in the relationship between the switching frequencies and the resonant …

An LC circuit, oscillating at its natural resonant frequency, can store electrical energy. See the animation. A capacitor stores energy in the electric field (E) between its plates, depending on the voltage across it, and an inductor stores energy in its magnetic field (B), depending on the current through it. If an inductor is connected across a charged capacitor, the voltage across the capacitor will driv…

About Photovoltaic Energy StorageThe capacitor self-resonant frequency causes your capacitor to stop behaving like a real capacitor and start behaving more like an inductor at high frequency. This important effect is unnoticeable at low frequencies, but it becomes a major problem related to signal …
About Photovoltaic Energy StorageThe operation of the switched capacitor can be explained using its voltage and current waveforms as shown in Fig. 2.The switching frequency of the switch M c is the same for the main switches as f s.This switch is turned on at t 0, where it is assumed that the turn-on time of the switch is synchronised with the zero crossing point of the current i 1.
