INPUT AC VOLTAGE CONTROL BI-DIRECTIONAL POWER CONVERTERS
First Claim
1. A bi-directional power converter fed by an input ac power source and providing an output to an electric load (which may have at least one energy storage element), said converter being able to handle active power, reactive power or both in a bi-directional manner, comprising:
- an input voltage control and regulator; and
wherein the voltage and current vectors of the said power converter are not restricted to 90 degrees.

Abstract
A family of power converters has input ac voltage regulation instead of output dc voltage regulation. The bi-directional converters control power flows and maintain the input ac voltage at or close to a certain reference value. These bi-directional power converters handle both active and reactive power while maintaining the input ac voltage within a small tolerance. Use of these converters is favorable for future power grid maintenance in that they (i) ensure the load demand follows power generation and (ii) provide distributed stability support for the power grid. The converters can be used in future smart loads that help stabilize the power grid.
