6 Frequently Asked Questions about “Parallel capacitor compensation model”
What are series-parallel (Sp) compensation topologies in capacitive power transfer (CPT)?
This paper analyzed the four series-parallel (SP) compensation topologies to achieve constant current (CC) and voltage (CV) output characteristics and zero phase angle (ZPA) input conditions with fewer compensation components in the capacitive power transfer (CPT) system. There are three main contributions.
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.
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 .
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.
What is a series compensated circuit?
The basic compensated circuits are composed of series (S) compensation, parallel (P) compensation, and series-parallel (SP) compensation, as shown in Figure 1. As the coupled capacitances of the coupler structure in the CPT system are usually the pF-level, the compensation inductors in the series compensated circuit would be large and heavy [ 29 ].
What is a parallel-parallel compensation system?
The major aim of designing parallel–parallel compensation systems is the implementation into one structure as many functions as possible. This is well-established in modern distribution systems where the nonlinear loads and external weather phenomena deteriorate power quality (PQ).
