“…Based on the idea of modifying the turn-off and turn-on procedure, a direct dc-link voltage control scheme was developed in [20,21]. Similarly, W. Suppharangsan proposed a modified switching technique to replace hysteresis control for dc-link capacitor minimization and verified its feasibility in [22]. However, the current rating for switches and diodes would increase by doing that.…”

This paper presents an integrated multi-port converter (IMPC) with capacitance reduction for switched reluctance machine (SRM). The conventional drive for SRM is based on an asymmetrical H-bridge which needs large capacitor on the dc bus to absorb the transient energy caused by current commutation. The proposed topology consists of a multi-port converter which introduces the dc bus capacitor as an extra port in addition to the input port and is integrated based on switch multiplexing technique. With such converter, the required capacitance can be reduced significantly by allowing an increase of the voltage ripple on the dc bus. In addition, the current commutation process can be accelerated with high-voltage dc bus because the dc bus voltage is adjustable. The requirement of capacitance in an asymmetrical H-bridge and the proposed topology is analyzed in detail. The corresponding control method for the presented converter is introduced briefly as well. Simulation results in Matlab/Simulink and experimental waveforms verified the feasibility of the proposed topology and its superior performance as compared with asymmetrical Hbridge converter.

Simple flux‐based Lagrangian formulation to model nonlinearity of concentrated‐winding switched reluctance motors

2015

View full text Add to dashboard Cite

Practical applications of switched reluctance motors (SRMs) require control techniques that can solve large torque ripple and large current ripple in power supply. To promote development of these techniques, a simple Lagrangian formulation for flux-based nonlinear SRM models is proposed. This formulation can be analysed in combination with Lagrangian circuit models of motor drivers. The properness of the formulation is supported by an example of the analysis of the operation of a simple SRM driving system.
