Circuit design of the primary side is decisive for the efficiency of inductive energy transmission. In order to maximise the transmitted energy to the load, primary side DC/AC inverter and system resonance topologies should be investigated. This paper presents an inverter for a multi-coil inductive system with different system resonance topologies for a low voltage and a relative high frequency of 1.2 MHz. A comparison between half-wave and full-wave inverters is carried out for both Series-Series (SS) and Parallel-Parallel (PP) topologies. Results show that the full-wave inverter with PP topology is adequate primary side circuit for multi-coil inductive system and reaches a sending power 10 times higher than a classical half wave inverter.
