This project was motivated by demand of our industrial partners for proposal of prospective control of induction machine drive for new generation of multisystem locomotives. This paper presents proposed drive control including specifically optimized PWM algorithms. Designed control is based on rotor flux oriented vector control in Cartesian coordinates which is unusually operated due to employed synchronized...
This paper describes design of a new control and PWM algorithms for a main drive of a multisystem locomotive with special focus on investigation into the trolley-wire current which could disturb railway safety systems. Designed control is based on rotor flux oriented vector control in Cartesian coordinates which is unusually operated due to specific PWM in whole speed range. We employ a synchronous...
This paper deals with the control of the output part of a power electronics converter, which we have designed for a diesel-electric power supply unit for military applications. The output part of the unit is composed of a four-leg three-phase voltage source inverter and a sinusoidal filter. The output part of the power supply unit with help of proposed control system allows to create three-phase symmetrical...
This paper deals with design of a new control system for a diesel-electric power supply unit, which output part is composed of a three-phase four-leg voltage source inverter. The main emphasis is given in this paper on employed modulation techniques. We are introducing two modulation strategies: 1) three- dimensional space vector PWM (3D-SVPWM) and 2) improved carrier-based PWM (CBPWM), which employs...
