As a brand of new power transfer system, contactless energy transmission system can be used to improve the security, dependability and flexibility of the power system. Contactless energy transmission technology is suitable for some special fields, so it has already been received the great concern of foreign academia and international engineering technological circle. Energy coupling realized by contactless magnetic tank transformer as new approach of rotator excitation in synchronous machine could replace brushes and slip rings of traditional excitation. This system reduces size, weight and cost of excitation system to great extent. First, a suitable model needs to be founded because contactless energy transfer system is different from the switching power supply. We found the mutual inductance model and then gived a detailed discussion on the loosely coupled magnetic tank transformer. In accordance with the condition of the most power transmission we use the harmonic technique to realize compensation and propose series-series topology. In order to obtain the stable system the harmonic frequency of primary zero phase angle and critical load resistance could be determined based on this circuit. Second, the ideal efficiency analysis mode was proposed to simplify efficiency analysis process. In this process, the ideal efficiency determined by load resistance was introduced into the expression of input and output power and made sure of the last efficiency of contactless excitation energy transmission system. Last, when the air gap and input signal frequency have been maintained, we study the impact on the contactless energy transmission efficiency when the input signal waveform and average power changes. We selected the square wave, sine wave and triangular wave as the input signals. It will provide certain reference for the performance analysis of magnetic tank transformer.
