Abstract: A controller for driving permanent magnet type synchronous motor. A motor terminal voltage or IPM (intelligent power module) input voltage necessary to achieve a target operating point is computed based on torque command and motor revolution. When the computed voltage exceeds an actual battery voltage, a booster is inserted between the battery and IPM, and the battery voltage, after being boosted, is applied between the direct current terminals of the IPM. Since the motor terminal voltage can be made so as to not exceed the boosted voltage even if the motor terminal voltage rises along with a rise in revolution and speed voltage, field weakening control becomes unnecessary.

Abstract: A boost circuit and method is described for supplying a boost voltage to a rotor of the electric machine, just as the electric machine is pulsed on, the boost voltage aids the rotor in quickly overcoming its start-up inductance, rapidly turn on the rotor. As a result, much faster transition times are realized each time the electric machine transitions from the off state to the on state at the start of a pulse. By reducing the transition time, the overall efficiency of the electric machine is significantly improved.
