| Abstract |
A PWM method for the control of a three-level inverter is described. Switching frequency optimal-PWM method (SFO- PWM) gives an optimal utilization of mean thyristor switching frequency permitted. The signal processing structure js simple. Though SFO-PWM is suited (or microprocessor applications, signal processing is described for an analogous model. Many applications of three-level-inverters work with a dc-link neutral point not stabilized from power input converter. A neutral point potential control is described, which is capable of stabilizing potential by varying the switching sequences of the three-level inverter itself. |
