Active stabilization of serially connected capacitors in high voltage applications |
摘要 |
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.
