6 FAQs about [Capacitors for parallel compensation]

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.

What are the types of compensation capacitors?

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.

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.
