    摘要： The present invention discloses a control method for the system gain of a UPS, which includes the steps of: S1: detecting a PFC unit so as to determine whether to start an LLC, and if so, then going to step S2; otherwise, going to step S8; S2: starting the LLC; S3: detecting the mains supply so as to determine whether to switch from the mains supply to a battery, and if so, then going to step S4; otherwise, going to step S5; S4: performing a frequency-fixed adjustment on the LLC with an operating frequency larger than a resonating frequency by a preset magnitude while clearing an integral quantity within a first preset time T1; and performing a frequency-fixed adjustment on the LLC with an operating frequency equal to the resonating frequency while clearing the integral quantity between the first preset time T1 and a second preset time T2, and going to step S8; S5: determining whether the LLC-in-series resonant converter has an overload, and if so, then going to step S6; otherwise, going to step S7; S6: performing a frequency-fixed adjustment on the LLC-in-series resonant converter with the operating frequency equal to the resonating frequency while clearing the integral quantity; and going to the step S8; S7: performing a normal PI adjustment on the LLC-in-series resonant converter; and S8: Ending. The operation condition of the PFC is detected in real time, the LLC is started when the PFC becomes abnormal, and the LLC is adjusted in response to a load during operating so that the system gain is maintained in a monotonously step-down region of a ZVS region.

    摘要翻译： 本发明公开了一种用于UPS的系统增益的控制方法，包括以下步骤：S1：检测PFC单元以确定是否启动LLC，如果是，则进入步骤S2; 否则，进入步骤S8; S2：启动LLC; S3：检测主电源，以确定是否从电源切换到电池，如果是，则进入步骤S4; 否则，进入步骤S5; S4：在第一预设时间T1内清除积分量的情况下，以大于谐振频率的工作频率在LLC上执行频率固定调整预定幅度; 以及在清除第一预设时间T1和第二预设时间T2之间的积分量的情况下，以等于谐振频率的工作频率对LLC进行频率固定调整，并进入步骤S8; S5：确定LLC串联谐振变换器是否有过载，如果是，则进入步骤S6; 否则，进入步骤S7; S6：在清除积分量的同时，将工作频率等于谐振频率的LLC串联谐振变换器进行频率固定调整; 并进入步骤S8; S7：在LLC串联谐振转换器上执行正常的PI调节; 和S8：结束。 PFC实时检测运行状态，当PFC变为异常时，启动LLC，并在运行期间根据负载调整LLC，使系统增益保持在单调降压区域 ZVS区域。

    摘要： A variable filter element and a variable filter module suitable for decreasing the drive voltage are provided. The variable filter element includes a substrate, two ground lines and a signal line between the ground lines, where these lines are disposed to extend in parallel on the substrate. The filter element further includes movable capacitor electrodes which bridge between the ground lines and have portions facing the signal line, drive electrodes which are located between the signal line and the ground lines and generate electrostatic attraction with the movable capacitor electrodes, and a ground line, which is disposed in the substrate, has a portion facing the signal line, and is electrically connected with the ground. The variable capacitor electrodes and the ground line constitute ground interconnection portions, and the signal line and ground interconnection portion constitute a distributed constant transmission line.
