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.
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 .
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.
Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.
This paper presents a family of Capacitive Power Transfer compensation topologies. According to the output requirements of targeted applications, the categorized compensation topologies are useful for selecting the appropriate one to achieve constant-voltage or constant-current characteristics.
It is shown that when the coupling capacitance drifts, the input power factor of the compensation topology in Group 1 drops sharply, while the other three compensation topologies are less affected. More importantly, when the coupling capacitance decreases, the input power factor of Group 4 keeps constant. Fig. 7.
