This paper presents a control scheme for variable speed operation of a high-speed turbogenerator which is connected to the mains by a voltage source converter. This control scheme allows for the use of a lookup table based control with a speed-power-characteristic or for the use of a maximum power point tracker. Presented measurements which were obtained from a successfully tested cogeneration system verify the calculated behaviour of the turbine.
