Abstract
A wind turbine generator controller suitable for off-grid application and a method of controlling a wind turbine generator. A generator speed signal indicative of power production potential and a load signal indicative of power being drawn by a load are used to generate a stall load signal that slows the generator if a power balance mismatch condition results from such factors as excessive wind or too light a load. The stall load may be a delta connected SCR bridge or a TRIAC connected across one or more elements of a rectifier that converts AC power from the generator to DC power.
