| Abstract |
The drive control with uP pulse pattern generator is described using the example of a traction drive for a trolley-bus with a GTO pulse width modulated inverter. The control process utilized corresponds to the dynamic demands with rise times of approximately 20 ms. It is based on stationary decoupled flux and torque control. The determination of an appropriate pulse pattern process for a drive system is dependent on the economically and technologically expedient switching frequency of the power semiconductors and the required level of voltage utilization which is derived from the rated motor voltage and the supply voltage of the converter. The value of the maximum motor frequency and the need of reducing the total harmonic distortion in current and torque complete the requirement profile of the pulse pattern generator. The realization was conducted in a two-processor
interconnected system. |
