Free QuoteThis 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.
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.
Parallel Active Power Compensators (APC) seem to have been a very widely discussed matter of many publications in the last 20 years [ 1 – 7 ]. The features of these devices can be considered in respect to a few aspects, such as power stage structure, reference current calculation and control method, overall cost of application, number of functions.
Two types of parallel compensators with the same control method but with different mode of operation are described and compared [ 33 ]. The hybrid solution composed of both types—voltage and current mode—is introduced to show the wide range of possibilities of modern power electronics applications.
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 ].
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).
