This paper proposes and implements a decoupled multichannel based wireless switched reluctance motor (WSRM) system with tunable compensation network (TCN) and multifrequency pulse density control (MPDC). In previous studies, several wireless motor systems have been proposed. However, there are still some issues such as cross interference, power balance and dynamic speed regulation that are not well considered. The proposed system firstly suppresses the cross interference between receivers via the resonant filters to reduce the coupling between multiple power channels. Then, the switch-controlled capacitor (SCC) are employed to implement a tunable compensation network to ensure power balance and load-independent output characteristics under multiple operation frequencies. Additionally, the speed regulation is realized by the proposed MPDC strategy, which achieves the commutation by switching the operation frequency and energizes the phase winding by adjusting the pulse density of the inverter. Finally, a 120 W prototype with 36 V input voltage is constructed and evaluated. The experimental results validate the improvement of the decoupled power channel and the feasibility of the proposed speed control method. The steady-state and dynamic performance of the proposed system are both tested. The efficiencies and losses of the system are analyzed and the peak efficiency of 83.58% is reached.
