Abstract
An elevator drive circuit is used for maintaining the voltage across first and second serially connected capacitors having first and second ends. The circuit comprises an active stabilizer for substantially maintaining a predetermined value of the voltage at a connection node of the capacitors. The active stabilizer provides compensation in response to deviations from the predetermined value of the voltage at the connection node.
