Abstract. The paper presents a squirrel-cage induction machine operating as a generator principally designed for use in small wind and

hydroelectric power stations. The main advantages of such a generator are its high reliability, low price and costs of operation and maintenance.

The asynchronous generator coupled to the grid through the AC/DC/AC converter is capable of generating energy even at low turbine speed.

The results of investigations on the AC/DC and DC/AC converters controlled by linear and nonlinear current regulators are also discussed.
