VSCF system with DC link harmonics control |
摘要 |
The problem of reducing harmonic content of AC bus voltage in a power system (10) is minimized using a controller (30) for a PWM inverter (38). The controller (30) develops a duty cycle command on a line (40) for controlling operation of the PWM inverter (38). The controller (30) develops the duty cycle command to maintain the PWM inverter output voltage at a desired level. This duty cycle command is modulated in accordance with the harmonic content evident on a DC bus (34) which supplies power to the PWM inverter (38).
