What are series-parallel (Sp) compensation topologies in capacitive power transfer (CPT)?

This paper analyzed the four series-parallel (SP) compensation topologies to achieve constant current (CC) and voltage (CV) output characteristics and zero phase angle (ZPA) input conditions with fewer compensation components in the capacitive power transfer (CPT) system. There are three main contributions.

How does a compensating capacitor affect power transfer?

When multiplied by the voltage across the load this leads to the same increased level of power, given by Eq. (22.6), as with parallel compensation. As shown by Eq. (22.6), compensating capacitors on the secondary side of an IPT circuit allow for an increase in power transfer by the Q of the secondary circuit.

Can parallel capacitors cause super synchronous resonances?

This solution is not feasible, since the amount of the grid impedance, thus its resonance frequency, varies depending on the operating conditions of the power system. The application of parallel compensation instead of series compensation is possible as well. But the parallel capacitors may cause super-synchronous resonances .

What is a compensating capacitor in an IPT circuit?

As shown by Eq. (22.6), compensating capacitors on the secondary side of an IPT circuit allow for an increase in power transfer by the Q of the secondary circuit. As for the secondary side of the circuit, primary side compensation is also beneficial, and reduces the reactive power drawn from the supply for a given power transfer level.

What is an enclosed capacitor bank?

Enclosed capacitor banks designed by Grid Solutions are used for power factor correction, voltage support, harmonic suppression and to maximize network capacity in industrial applications and distribution systems. They supply individual, group or central reactive power compensation of fluctuating loads in three-phase networks up to 36 kV.

Does a capacitive coupler reduce reactive power in a CPT system?

A capacitive coupler structure would induce significant reactive power in the CPT system, degrading the power transfer capability [20, 21, 22]. Therefore, the compensation topologies play an essential role in eliminating the reactive power induced by the capacitive coupler [23, 24, 25, 26].
