What is a compensating capacitor?

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.

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.

How a capacitor compensation circuit is controlled?

Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.

Can parallel capacitors cause super synchronous resonances?

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 .

Can parallel compensation be used instead of series compensation?

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.

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. 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.
