  • Active Filters

    Power conversion by virtue of its basic role produces harmonics due to theslicing of either voltages or currents. To a large extent the pollution in theutility supply and the deterioration of the power quality has been generatedor created by non-linear converters. It is therefore ironic that power c ...

  • PCB设计问题集锦

    PCB设计问题集锦 问:PCB图中各种字符往往容易叠加在一起,或者相距很近,当板子布得很密时,情况更加严重。当我用Verify Design进行检查时,会产生错误,但这种错误可以忽略。往往这种错误很多,有几百个,将其他更重要的错误淹没了,如何使Verify Design会略掉这种错误,或者在众多的错误中快速找到重要的错误。    答 ...

  • MR16 LED驱动MR16 LED灯与电子变压器兼容

    Abstract: There are differences between the operation of low-frequency AC transformers and electronic transformersthat supply current to MR16 lamps, and there are also differences in the current draw for MR16 halogen lamps andMR16 LED lamps. These contrasts typically prevent an MR16 LED lamp from ...

  • 利用高压看门狗定时器加强汽车安全系统

      Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" ...

  • DUAL DIGITAL ISOLATORS

    The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are orientedin the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic inputand output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier ...

    This example shows how to update at regulate period the WWDG counter using theEarly Wakeup interrupt (EWI). The WWDG timeout is set to 262ms, refresh window set to 41h and the EWI isenabled. When the WWDG counter reaches 40h the EWI is generated and in the WWDGISR the counter is refreshed to prevent ...
