Title: Method for reducing undesired currents in an electrical power generation system

Abstract

An electrical power generation system is provided, and a method of reducing undesired currents therein. The method includes the steps of delivering current via at least one variable frequency switching means, and adjusting a switching frequency of the at least one variable frequency switching means based on the power output of the system. The system may further include an electronic controller having a control algorithm recorded thereon, the control algorithm including means for adjusting the variable frequency switching means based on a power output of the system.
