Electronic control apparatus |
摘要 |
An electronic control apparatus for controlling currents supplied to star-connected multiphase loads. The apparatus has two sets of switching means, a reference signal source, a voltage detector for detecting the voltage of the common terminal of the star-connection, a comparator for comparing the outputs of the voltage detector and the reference signal source, a feedback amplifier for amplifying the output of the comparator, a load current supplying means for supplying a current to the multiphase loads through one set of the two sets of the switching means according to a command signal, a feedback current draining means coupled to the feedback amplifier and the other set of the two sets of the switching means, and a timing signal generator for selectively switching the two sets of the switching means, wherein the feedback current draining means drains the current through said other set of switching means from the multiphase loads so as to keep the voltage at the common terminal of the star connection constant or substantially constant regardless of the mode of the timing signal generator.
