  1. Technical Discussion
    I was searching for a high side current sensor similar to the Microchip HV7800, and found the IR25750, which has a novel way of monitoring the current in a MOSFET or IGBT by using the RdsON voltage while it is conducting. It probably works best for a MOSFET which has a relatively linear bulk...
  2. Controllers
    I just happened upon an informative article about high voltage reflectred waves resulting from PWM drives and the interaction of the high frequency waveforms with the cables and the motor insulation and inductance: http://www.ab.com/support/abdrives/documentation/techpapers/ieee/pcic.pdf This...
