ABSTRACT
Multiple energy-storage element resonant power converters (x-element RPC) are the sixth generation converters. As the transfer power becomes higher and higher, traditional methods are unable to deliver large amounts of power from the source to the final actuators with high efficiency. In order to reduce the power losses during the conversion process the sixth generation converters — multiple energy-storage elements resonant power converters (x-element RPC), were created. They can be classified into two main groups
• DC/DC resonant converters • DC/AC resonant inverters
Both groups consist of multiple energy-storage elements: two, three, or four elements. These energy-storage elements are passive parts: inductors and capacitors. They can be connected in series or parallel in various methods. The circuits of the multiple energy-storage elements converters are
• Eight topologies of two-element RPC shown in Figure 13.1. • Thirty-eight topologies of three-element RPC shown in Figure 13.2. • Ninety-eight topologies of four-element (2L-2C) RPC shown in
Figure 13.3.
