Preliminary
80-Lead 64-Lead 3-Sided Ceramic Gullwing
Plastic Gullwing
Die General Description
The HV506 is a low-voltage serial to high-voltage parallel con-verter with push-pull outputs. It is especially suitable for use as a symmetric row driver in AC thin-film electroluminescent (ACTFEL) displays.
When the data reset pin (DR IO ) is at logic high, it will reset all the outputs of the internal shift register to zero. At the same time, the output of the shift register will start shifting a logic high from the least significant bit to the most significant bit. The DR IO can be triggered at any time. The DIR pin controls the direction of data through the device. When DIR is at logic high, DR IOA is the input and DR IOB is the output. When DIR is grounded, DR IOB is the input and the DR IOA is the output. See the Output Sequence Operation Table for output sequence. The POL and OE pins perform the polarity select and output enable function respectively. Data is clocked through the shift register loaded on the low to high transition of the clock. A logic high in the shift register will cause the other corresponding output to swing to V DD if POL is high, or to V SS if POL is low. All other outputs will be in the High-Z state.If OE is at logic high all outputs will be in the High-Z state. An output in the High-Z state may block up to 275V above V SS or 275V below V DD . The D P /D N pins are for the positive/negative discharge of the high voltage output HV OUT . Data output buffers are provided for cascading devices.

1磁芯损耗:正弦波与矩形波比较
一般情况下,磁芯损耗曲线是按正弦波+/-交流(AC)激励绘制的,在标准的和正常的时候,是不提供极大值曲线的。涉及到开关电源电路设计的一个共同问题是正弦波和矩形波激励的磁芯损耗的关系。对于高电阻率的磁性材料如类似铁氧体,正弦波和矩形波产生的损耗儿乎是相等的,但矩形波的损耗稍微小一些。材料中存在高的涡流损耗(如大
一般情况下,具有矩形波的磁芯损耗比具有正弦波的磁芯损耗低一些。但在元件存在铜损的情况下,这是不正确的。在变压器中,用矩形波激励时的铜损远远大于用正弦波激励时的铜损。高频元件的损耗在铜损方面显得更多,集肤效应损耗比矩形波激励磁芯的损耗给人们的印象更深刻。举个例子,在
20kHz、用17#美国线规导线的绕组时,矩形波激励的磁芯损耗儿乎是正弦波激励磁芯损耗的两倍。例如,对于许多开关电源来说,具有矩形波激励磁芯的
5V、20A和30A输出的电源,必须采用多股绞线或利兹(Litz)线绕制线圈,不能使用粗的单股导线。
2 Q值曲线
所有磁性材料制造厂商公布的Q值曲线都是低损耗滤波器用材料的典型曲线。这些测试参数通常是用置于磁芯上的最适用的绕组完成的。对于罐形磁芯,Q值曲线指出了用作生成曲线时的绕组匝数和导线尺寸,导线是常用的利兹线,并且绕满在线圈骨架上。

如何理解中港税收协定中不动产占资产50%规定
问:A公司的香港股东H公司将持有A公司(持股比例一直低于25%)的股票出售。根据《国家税务总局关于执行〈内地和香港特别行政区关于对所得避免双重征税和防止偷漏税的安排〉第二议定书有关问题的通知》(国税函[2008]685号)规定,H公司出售A公司股权的收益应当回香港征税。
问题:1、关于A公司的不动产占资产比例要低于50%,H公司的转股收益才能回香港征税。不动产是占总资产比例低于50%,还是不动产占净资产比例低于50%,才能享受优惠?
2、《国家税务总局关于税收协定中财产收益条款有关问题的公告》(国家税务总局公告2012年第59号)第三条规定,“中新税收协定”第十三条第四款以及“国税发[2010]75号所附条文解释”所述的公司财产和不动产均应按照当时有效的中国会计制度有关资产(不考虑负债)处理的规定进行确认和计价,但相关不动产所含土地或土地使用权价值额不得低于按照当时可比相邻或同类地段的市场价格计算的数额。
那么,根据这份条文的“(不考虑负债)”是不是指不动产占净资产比例低于50%? 答:《内地和香港特别行政区关于对所得避免双重征税和防止偷漏税的安排》第十三条第四款规定,转让一个公司股份取得的收益,而该公司的财产主要直接或者
间接由位于一方的不动产所组成,可以在该一方征税。
第五条规定,转让第四款所述以外的任何股份取得的收益,而该项股份相当于一方居民公司至少25%的股权,可以在该一方征税。
《内地和香港特别行政区关于对所得避免双重征税和防止偷漏税的安排第二议定书》规定第四条,《安排》第十三条第四款及议定书第二条提及的公司财产不少于百分之五十由位于一方的不动产所组成,按以下规定执行:
在股份持有人转让公司股份之前三年内,该公司财产至少百分之五十曾经为不动产。
第五条规定,取消《安排》第十三条第五款的规定,用下列规定代替:
五、除第四款外,一方居民转让其在另一方居民公司资本中的股份或其他权利取得的收益,如果该收益人在转让行为前的十二个月内,曾经直接或间接参与该公司至少百分之二十五的资本,可以在该另一方征税。
《中华人民共和国政府和新加坡共和国政府关于对所得避免双重征税和防止偷漏税的协定》第十三条第四款规定,转让一个公司财产股份的股票取得的收益,该公司的财产又主要直接或者间接由位于缔约国一方的不动产所组成,可以在该缔约国一方征税。
第五条规定,转让第四款所述以外的其他股票取得的收益,该项股票又相当于缔约国一方居民公司百分之二十五的股权,可以在该缔约国一方征税。
根据上述规定,中港税收协定中的第十三条第四款、第五款规定的内容与中新税收协定中规定的内容不一致,中港税收协定中该条款的解释及执行不能按中新税收协定对应规定执行。
《国家税务总局关于执行〈内地和香港特别行政区关于对所得避免双重征税和防止偷漏税的安排〉第二议定书有关问题的通知》(国税函[2008]685号)第二条关于公司财产主要由不动产所组成的判定问题规定,第二议定书第四条有关股份持有人转让公司股份行为前三年内公司财产至少百分之五十曾经为不动产的规定,换函第二条明确执行时按纳税年度终了时的账面数据进行判定。
因此,如果该香港H公司为受益所有人,其持有境内A公司股票一直都低于25%。如果H公司转让A公司股票之前三年内,按纳税年度终了时的账面数据进行判定A公司的财产至少百分之五十曾经为不动产的,H公司取得的股票转让收益应在境内申报缴纳企业所得税;否则,H公司转让股票收益可享受协定待遇,在境内免征企业所得税。
所述“A公司的财产至少百分之五十曾经为不动产”,是指A公司的资产总额至少百分之五十曾经为不动产,而不是指A公司的净资产。即不动产占企业资产总额的比例曾经不低于50%。
