The voltage on primary parallel compensation capacitor rises to source voltage instantaneously when the voltage polarity changes, causing instant large current and impairing capacitor lifespan.
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 .
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.
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.
To cancel the leakage inductance, compensating capacitors are attached in parallel or series to reduce the circulation of high reactive current (Barman et al., 2015; Houran et al., 2018). As a result, for the primary (Tx) coil of the WPT system, the main role of compensation capacitor is to reduce the VA rating of the input source.
In order to achieve the resonance state, a compensation capacitor could be externally attached in series or parallel on the transmitting (primary) or receiving (secondary) side.
