Abstract
An active rectification system includes an active rectifier, a pulse width modulation (PWM) control, and a closed loop vector control. The PWM control portion is configured to control switching of the active rectifier and the closed loop vector control is configured to generate the required duty cycles for the PWM signals that regulate the DC voltage output and force a three-phase current input of the active rectifier to align with a three-phase pole voltage input of the active rectifier.
Claims10
An active rectification system, comprising:
- an active rectifier;
- a pulse width modulation (PWM) control portion, wherein the PWM control portion is configured to control switching of the active rectifier;
- and
- a closed loop vector control that is configured to determine a q-component reference current as a function of a d-component reference current and d-q voltage components of pole voltage input of the active rectifier, wherein the closed loop vector control is configured to generate required duty cycles for PWM signals for the PWM control portion, the required duty cycles regulate the DC voltage output and force a three-phase current input of the active rectifier to align with the pole voltage input of the active rectifier.
