Abstract

A power conversion system can be implemented to reduce load disturbances on a DC bus which may be caused by load activity, such as a motor starting, stopping and/or ramping up or down. In one aspect, the power conversion system can receive externally supplied multi-phase AC electric power, such as three-phase power from a power grid, and use a converter circuit to generate the DC bus. The power conversion system can then use an inverter circuit to generate multi-phase AC electric power from the DC bus for driving the load with adjustable frequencies and/or amplitudes as desired. The power conversion system can receive feedback signals to sense the load activity and adjust the converter and/or inverter circuits accordingly to reduce the load disturbances on the DC bus.
