    • A method for operating a line-side fundamental-frequency-clocked converter is disclosed. The converters has a bridge circuit with, for example three, upper and, for example three, lower semiconductor switches, which are connected to respective positive and negative terminals of a DC link circuit. Center taps of connected pairs of the upper and lower semiconductor switches are connected to the line voltage phases. Two upper or two lower semiconductor switches are simultaneously activated during fundamental frequency operation for a predetermined time period before or after a natural trigger instant of the semiconductor switches caused by a line voltage angle. An estimated line voltage angle for clocking the semiconductor switches is tracked based on two phase currents measured while the two upper or two lower semiconductor switches are simultaneously active.
    • 公开了一种用于操作线路侧基频时钟转换器的方法。 转换器具有桥接电路,其具有例如三个上部和(例如三个)下半导体开关,其连接到DC链路电路的相应的正极和负极端子。 上下半导体开关的连接对的中心抽头连接到线路电压相位。 在由线电压角度引起的半导体开关的自然触发时刻之前或之后的预定时间段内,在基频操作期间,同时激活两个上或下两个半导体开关。 基于在两个上半导体开关或两个下半导体开关同时有效时测量的两相电流来跟踪用于计时半导体开关的估计线电压角。

    • A process for producing a dental prosthesis includes producing a wax prosthesis including artificial teeth and a receiving bed for articulating the artificial teeth by inserting the artificial teeth into the receiving bed at anatomically correct positions, producing a negative mold of the wax prosthesis using a duplicating medium, removing the receiving bed, introducing a fixing material into the negative mold, and allowing the fixing material to set, so that the undersides of the artificial teeth are permanently embedded in the fixing material. The artificial teeth have a holding groove running in a mesio-distal direction on its underside, so as to produce reliable positively locking joining of the artificial tooth to the receiving bed of the wax prosthesis.
    • 一种用于制造牙科假体的方法包括制造包括人造牙齿的蜡假体和用于通过将解剖学上正确位置处的人造牙插入到接受床中来铰接人造牙的接收床,使用复制介质产生蜡假体的阴模 ,移除接收床,将固定材料引入负模具中,并使固定材料固定,使得人造牙齿的下侧永久地嵌入固定材料中。 人造牙具有在其下侧沿中间远端方向延伸的保持槽,以便可靠地将人造牙齿与蜡假体的接收床正确地锁定在一起。
