There are four compensation circuits in the WPT system that are most common, namely: series-series (S-S), series-parallel (S-P), parallel-parallel (P-P), and parallelseries (P-S) [13, 14]. Soft ...
Among them, the more popular schemes include passive filter (PF), parallel capacitor compensation, static reactive power compensation device, complete set of power capacitor compensation devices, and so on. Although the passive filter can compensate for harmonics, it is susceptible to the influence of parameters and resonance problems.
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.
The application of parallel compensation instead of series compensation is possible as well. But the parallel capacitors may cause super-synchronous resonances . Therefore, when there is the possibility of using a combination of series and parallel compensation, its application can be a good solution.
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 .
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.
The authors note that the parallel compensation circuit is easier to set up and performs better than the series compensation circuit. Figure 19.10.
