Analysis of a Hybrid Excitation Switched Reluctance Generator Based on Boost Converter

This paper mainly analyze the power generation performance of SHSRM in the general separately excited converter and the separately excited boost converter. When the excitation voltage is constant, the power generation can only be adjusted by changing the turn-on and turn-off angles. This paper proposes a new type of separately excited converter for separately excited power generation of SHSRM. Firstly, the power generation characteristics of separately excited mode is analyzed, the power generation voltage-current ratio is used as the measure standard of power generation performance to find the optimal turn-on and turn-off angle of SHSRM in separately excited modes. Then analyzing the working modes of the separately excited boost converter, which can provide additional transient voltage to improve the power generation performance. Simulation and experiments show that the separately excited boost converter can greatly improve the power generation performance of SHSRM.
