LC Circuit: Definition, Types, Resonance, and Formula

Parallel LC Circuit. In a parallel LC circuit, the inductor and capacitor are connected side by side, forming two separate branches. It means that the current flowing through the inductor is different from the current flowing through the capacitor. The capacitor stores energy in an electric field when it is charged, while the inductor

An active equalization method for series-parallel battery pack

lithium-ion batteries are widely used in high-power applications, such as electric vehicles, energy storage systems, and telecom energy systems by virtue of their high energy density and long cycle life [1], [2], [3].Due to the low voltage and capacity of the cells, they must be connected in series and parallel to form a battery pack to meet the application requirements.

About Us

Our Vision is the successful application of advanced, high-temperature molten salt technology as a thermal storage medium for large-scale solar energy systems..

Parallel Resonance Circuit

A parallel circuit containing a resistance, R, an inductance, L and a capacitance, C will produce a parallel resonance (also called anti-resonance) circuit when the resultant current through the parallel combination is in phase with the supply voltage. At resonance there will be a large circulating current between the inductor and the capacitor due to the energy of the oscillations,
