Abstract: PURPOSE:To safely switch brake mode and power mode in an induction motor by applying an arcing command to a thyristor in response to the potential detected output of a free wheeling circuit when switching the modes. CONSTITUTION:The primary voltage is controlled by firing thyristors 5-10 at normal rotation (power mode) time and thyristors 7, 8, 11-14 at reverse (power mode) time.
