Abstract

PURPOSE:To protect main circuitry in an inverter, by switching motor windings without supplying power and starting current flow upon confirmation of reliable switching, thereby suppressing overvoltage and over current. CONSTITUTION:When motor windings are switched, a controller 12 controls an inverter to restrict motor voltage. Upon finish of voltage restriction, current is interrupted. Then a winding switching signal is outputted from the controller 12. Consequently, switches 31, 32 function to switch the windings. Thereafter, interruption of current is released to rise the current level slowly from initial level to a necessary level.
