    • PROBLEM TO BE SOLVED: To provide actuation systems and lithographic apparatus which address the issue of uncontrolled return of common mode currents, and to prevent the occurrence of corona and discharge between high voltage electric cables in low pressure environments in a main embodiment.SOLUTION: An exemplary actuation system comprises an actuator module, a power source and power transmission cables. The actuator module includes an electrical motor and a first plurality of shielded cables configured to connect to the electrical motor at one end. The actuator module is located in a low pressure environment and each shield of the first plurality of cables is grounded. The transmission cables electrically connect the first plurality of cables with power supply, and comprise an extra cable which is configured to connect each shield of the first plurality of cables with the first extra cable, via a choke so as to provide a return path for common-mode currents.
    • 要解决的问题:提供解决共模电流不受控制返回问题的致动系统和光刻设备,并且在主要实施例中防止在低压环境中的高压电缆之间发生电晕和放电。 解决方案:示例性致动系统包括致动器模块,电源和电力传输电缆。 致动器模块包括电动马达和被配置为在一端连接到电动马达的第一多个屏蔽电缆。 致动器模块位于低压环境中,并且第一多个电缆的每个屏蔽件接地。 传输电缆将第一多个电缆与电源电连接,并且包括额外的电缆,其被配置为经由扼流圈将第一多个电缆的每个屏蔽件与第一附加电缆连接,以便提供用于共用的返回路径 模式电流。 版权所有(C)2012,JPO&INPIT
