In order to verify the performance of the system, motor speed regulation experiments were carried out under different control modes and operating conditions. According to the application of switched reluctance motor system in photovoltaic pump, a new structure of switched reluctance motor system is proposed, which can realize the new energy battery with only one set of power converters. The energy conversion between the energy storage and the switched reluctance motor (SRM) and the function of maximum power point tracking. Through the research of circuit working mode, control principle, simulation and experiment, the validity of the system in photovoltaic array single power supply mode, battery charging mode and hybrid mode is verified. Aiming at the application of switched reluctance motor system in charging without charging piles, a new on-board charging circuit structure based on inductance reuse of motor windings is proposed, which can work in both Buck mode and Boost mode. At the same time, the constant current charging can be realized by means of PI control strategy, which can meet the charging requirements of different voltage levels and improve the charging efficiency.

Switched reluctance motor (SRM) has more application space and direction in the new energy field besides photovoltaic pump and charging without charging pile. The circuit structure, control mode and research ideas presented in this paper are helpful to the further application of switched reluctance motor in the field of new energy.
