Abstract: When an abnormality occurs in a first voltage sensor that detects a voltage of a power line on a high voltage side or a second voltage sensor that detects a voltage of a power line on a low voltage side, an estimated voltage of the power line on the high voltage side is calculated based on a detected current of a reactor that is detected by a current sensor that detects a current of the reactor as the detected current, and a step-up converter is controlled using the estimated voltage of the power line on the high voltage side.

Abstract: A fuel cell system to be mounted on a vehicle includes: a fuel cell for generating electric power by using reactant gas; a secondary battery capable of charging and discharging electric power; a converter electrically connected between a drive motor for driving the vehicle and the secondary battery to perform voltage conversion between the drive motor and the secondary battery; and a controller for controlling the fuel cell system. The controller exerts such control that when an accelerator for accepting a speed control instruction for the vehicle has accepted a deceleration instruction under a condition that a charge rate of the secondary battery is equal to or more than a preset value, or when the accelerator has accepted a deceleration instruction under a condition that a chargeable electric power of the secondary battery is equal to or less than a preset value, electric power is discharged from the secondary battery during a period of power-running operation lasting until the drive motor with its torque being decreased shifts to regenerative operation. Thus, increases in frequency at which the auxiliary machine is operated to consume regenerative power can be suppressed.

Abstract: A trans inductor having a powdery magnetic substance and a power converter using the trans inductor are provided. The trans inductor and the power converter reduce peak current flowing in an inverter power module (IGBT), improve inverter efficiency, reduce output RMS current (output effective current) and reduce capacitor consumption by applying a material with properties that are resistant against current saturation instead of a core material of a conventional trans inductor employed in a power converter. Accordingly, an inductance decreasing rate due to core saturation when high current is generated is improved and current flowing in a switch device is prevented from being abruptly increased.

Abstract: A LPF extracts DC component of a current detection value of an inverter input current. A subtracting section 4 calculates a difference between a current command value and the DC component of the current detection value. A current controller 5 produces two-phase PWM signals Sa and Sb complementary to each other, from the current difference. Further, an integrating circuit 7 integrates output terminal voltages Vu, Vv and Vw of the inverter to convert the output terminal voltages Vu, Vv and Vw into a magnetic-flux information Φu, Φv and Φw. A logic conversion section 8 converts the magnetic-flux information Φu, Φv and Φw into 120-degree conduction patterns S1′-S6′ to output the 120-degree conduction patterns S1′-S6′. Then, a logic circuit section 9 executes a logic synthesis between the PWM signals Sa and Sb and the 120-degree conduction patterns S1′-S6′ to output gate signals S1-S6.

Abstract: A three-phase regenerative drive (20) is operated based upon power from a single-phase AC source (12) and power from a DC source (14). The single-phase AC input power and the DC input power are converted to DC voltage on a DC bus (24) by a three-phase converter (22). DC power is provided from the DC bus (24) to a three-phase inverter having outputs connected to a motor (34). A controller (44) controls operation of the three-phase converter (22) based upon contribution factors of the AC and DC sources (12, 14) during motoring and regeneration. The controller (44) also controls an AC component of current from the DC source to reduce ripple current on the DC bus (24).
