| Abstract |
Self-extinction devices such as GTO thyristors provide the possibility to set up current-source inverters with sinusoidal inputs and outputs. For a high quality drive the resonant circuit made up with the capacitors at the inverter terminals and the machine inductances has to be kept under control. With an on-line calculation of the PWM switching times, not only the voltage but also the current is kept very close to the reference value, although the switching frequency is limited to a low maximum value. Measurements show the practicability of the suggested control scheme with the results of a low noise but high dynamic drive. |
