Fault Tolerant Modular Inductive Power Transfer System Design Using
In this paper, a design for an inductive power transfer system with a
series-series topology with an intermediate resonator is discussed. The
proposed method is an improved method that is derived from a
conventional IPT system design. While it is applicable for a wide range
of different operations, a contactless slip ring design is the main
system under investigation. The idea behind adding a resonator coil is
to achieve fault tolerance where the system can operate under various
open-circuited fault conditions. The proposed system is a two
transmitter and four receiver with an intermediate resonator system
where the Rx modules are connected parallel to a common DC-bus.
The system is found to be fault-tolerant to Rx side open circuit faults.
For normal operation at rated power, 90.6\% efficiency
