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 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.
The authors note that the parallel compensation circuit is easier to set up and performs better than the series compensation circuit. Figure 19.10. Series and parallel compensation circuits for IPT stage lighting. An effective method to charge the battery in electric vehicles is essential for the deployment of large numbers of vehicles on the road.
The secondary coil of an IPT system with parallel compensation is illustrated in Fig. 22.4 A, for which the capacitance, C, is chosen to resonate with LS at the circuit operating frequency. For ease of analysis, the Norton equivalent circuit can be derived, and is shown in Fig. 22.4 B.
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.
