Lc resonant energy storage

How LC tank is used in resonant circuit?

Here, a single LC tank is used as an energy carrier for voltage balancing, so small parasitic resistance is formed in the inductor (L) in the resonant circuit. In this circuit, cell 1 and cell n are associated with single nMOSFET switches, and cell 2 to cell n-1 are connected with bidirectional nMOSFET switches.

What is a resonant tank network?

Resonant tank network (RTN) Resonant tank (RTN), which is also known as resonant circuit, tuned circuit, or LC circuit, contains reactive elements which store vacillating energy at the circuit's resonant frequency. The resonance in the LC circuit is achieved by the energy movement between the inductor and the capacitor.

What causes resonance in LC circuit?

The resonance in the LC circuit is achieved by the energy movement between the inductor and the capacitor. When the capacitor loses its electromagnetic energy, the inductor is electromagnetically charged because energy moves from the former to the latter.

What is path resistance in LC resonant circuit?

Mostly path resistance is from MOSFET switches and inductors of the LC tank. Here, a single LC tank is used as an energy carrier for voltage balancing, so small parasitic resistance is formed in the inductor (L) in the resonant circuit.

What are the challenges and limitations of series resonant converters?

These challenges and limitations are summarized as below. Series resonant converters are unable to provide output voltage that is higher than the input voltage, which makes them not applicable in high voltage applications. In addition, in case of light load or no-load condition, it is difficult to control the output voltage.

Does charge balancing affect resonant L and C?

During the charge balancing time, there is no loading effect on resonant L and C. If the switching frequency increases or decreases, then series L and C face voltage and current stress. Fig. 10. Experimental waveform of the proposed circuit.
