| Abstract |
In electrical drive systems parasitic capacitances are forming resonant circuits in combination with the inductances of the system. A bidirectional drive system consists of at least one line side and one motor side inverter. Each inverter switching operation is stimulating common-mode oscillation in system resonant circuits. An active damping strategy reducing common-mode currents and voltages by influencing the pulse patterns of the inverters is presented in this paper. The method is based on a direct current control which is implemented in an FPGA. Results of the investigation are proved by experimental results and compared to a classical SV-PWM (without damping features). In addition, a method to analyse resonant circuits is introduced. |
