A first node is boosted up based upon a carry signal or the vertical start signal from a previous stage. A gate signal that is pulled up is outputted through an output terminal of a present stage based upon a first clock signal which is boosted up. An off-voltage is outputted through the output terminal of the present stage in response to an output signal from a next stage or the vertical start signal. The first node is discharged in response to the output signal from the next stage or a carry signal from a last stage. A positive ripple voltage at the first node is removed by providing a negative ripple voltage to the first node.申请人：Yeong-Keun Kwon,Sang-Jin Jeon,Yoon-Jang Kim,Bae-Heuk Yim,Bon-Yong Koo 地址：Suwon-si KR,Suwon-si KR,Suwon-si KR,Asan-si KR,Asan-si KR国籍：KR,KR,KR,KR,KR更多信息请下载全文后查看。
MAGNETICALLY IMMUNE GATEDRIVER CIRCUIT
专利名称：MAGNETICALLY IMMUNE GATEDRIVERCIRCUIT发明人：Pallesgaard, Stig Lund申请号：EP18195955.2申请日：20180921公开号：EP3477665A1公开日：20190501专利内容由知识产权出版社提供专利附图：摘要：A gatedriver circuit for controlling a power electronic switch. The circuitprovides a galvanic separation and is magnetically immune. The gatedriver circuitcomprises a transformer arranged with two separate cores of magnetically conductivematerial each forming a closed loop. A first electrical conductor has windings around a part of both cores, and a second electrical conductor also has windings around part of both cores. The two cores are positioned close to each other to allow mutual magnetic interaction. The windings of the first and second electrical conductors around the first core have the same winding direction, and the windings of the first and second electrical conductors around the second core have opposite winding direction of the windings of the first and second electrical conductors around the first core, so as to counteract electric influence induced by a common magnetic field through the closed loops of the first and second cores. Hereby, such gatedriver circuit is suitable for controlling power switches in environments with strong magnetic fields, e.g. inside a high power wind turbine.申请人：VESTAS WIND SYSTEMS A/S地址：Hedeager 42 8200 Aarhus N DK国籍：DK代理机构：Vestas Patents Department更多信息请下载全文后查看。

The present invention is a drive circuit for driving a plurality of switching elements (6, 7) that constitute one arm (5b) of an upper and lower arm circuit (5a), that have mirror periods different from each other, andthat are connected in parallel, wherein the drive circuit is provided with comparison units (26, 36) and shut-off units (27, 37). The comparison units compare an electrical current correlation value that correlates with an electrical current flowing in each of the plurality of switching elements with a threshold value for determining that a short circuit has occurred in another arm constituting the upper and lower arm circuit. The shut-off units turn off a switching element satisfying a condition that a state in which the electrical current correlation value exceeds the threshold value continues even after the end of a prescribed filter period. The filter period is set according to the length of the mirror period such that the shorter the mirror period of a switching element is, the shorter the filter period of the switching element is.申请人：DENSO CORPORATION,株式会社デンソー地址：1-1, Showa-cho, Kariya-city Aichi 4488661 JP,〒4488661 愛知県刈谷市昭和町１丁目１番地 Aichi JP国籍：JP,JP代理人：JIN Shunji,金順姫更多信息请下载全文后查看。
