Abstract: A power converter according to embodiments includes a boost circuit, a single-phase inverter, a current controller, and a power conversion controller. The current controller generates a voltage reference based on a difference between current output from the single-phase inverter and a current reference. The power conversion controller controls the single-phase inverter to generate a first portion of the AC voltage, and controls the boost circuit to generate a second portion of the AC voltage. The first portion corresponds to the voltage reference of which an absolute value is smaller than the voltage of the DC power supply. The second portion corresponds to the voltage reference of which an absolute value is greater than the voltage of the DC power supply.

Abstract: A controlling apparatus for an electric motor according to an embodiment includes a superposed component generator, an inverter, a current detector, and a magnetic pole position estimator. The superposed component generator generates, at a predetermined cycle, a superposed voltage reference of which vector is shifted by 90 degrees with respect to that of a superposed voltage reference previously generated, in a coordinate system that is set to a stator of the electric motor. The inverter outputs a driving voltage that is based on a driving voltage reference superposed with the superposed voltage reference to the electric motor. The current detector detects currents flowing into respective phases of the electric motor, and outputs the detected currents. The magnetic pole position estimator detects the magnetic pole position of the electric motor based on an amount of change in the detected currents at the predetermined cycle.
