Abstract
A device includes an active rectifier () having control gates controllable to produce an output voltage on a DC bus (), a gate control circuit () for producing gate control signals for controlling the active rectifier control gates, a first circuit () connected to the gate control circuit () for producing a command current magnitude signal and a power factor signal for use by the gate control circuit (), a current line () providing a signal related to the DC load current to the first circuit (), and a voltage line () providing a signal related to the DC bus voltage to the first circuit (). The first circuit () includes a command current magnitude signal generator () producing the command current signal based on the DC load current and a power factor controller () producing the power factor signal. The power factor controller () includes a feed forward circuit () for increasing the power factor signal in response to current fluctuations on the current line (). Also a method of controlling a voltage on a DC bus with the device.
