    Abstract: The main electric power source is connected to a lower-voltage side of a DC/DC converter by a first switch, and an electrical double-layer capacitor and a regulator circuit is connected to a higher-voltage side of the DC/DC converter. In addition, permanent magnets are disposed on a rotor so as to generate a magnetic field that is in a reverse direction to excitation by a field coil inside a claw-shaped magnetic pole portion of the rotor. A power supply control circuit controls opening and closing of the first switch so as to be in an open state when the engine is at rest, and so as to be set to a connected state after the regulator circuit is operated to make the alternator generate electric power to precharge the electrical double-layer capacitor after the engine is started.

    Abstract: There is provided a controller for a load drive system which can reduce a ripple current which flows in a smoothing capacitor even when an inverter is PWM controlled with a two-phase modulation.A controller for a load drive system having a converter for changing an output voltage of a DC power supply, an inverter for transforming a DC voltage outputted from the converter into a three-phase AC voltage to be applied onto a load and a smoothing capacitor provided in parallel between the converter and the inverter includes an inverter controller for PWM controlling the inverter with a two-phase modulation and a converter controller for PWM controlling the converter. Frequencies of an inverter carrier signal used in the inverter controller and a converter carrier signal used in the converter controller are the same.

    Abstract: A motor controller for an axial-gap motor permits a reduced size of the entire system of including a drive circuit and a power source of the motor, reduced cost, and higher reliability to be achieved by controlling the energization mode of the motor. The motor controller has a torque command determiner which inputs a first DC voltage to a first inverter at least either when a rotor is at a halt or when the number of revolutions of the rotor is a predetermined number of revolutions or less, supplies a field axis current for changing the magnetic flux of a field of the rotor to a first stator from the first inverter such that the amount of energization is temporally changed, converts an induced voltage developed in a second stator by the supplied field axis current into a second DC voltage by a second inverter, and outputs the second DC voltage, thereby charging a second battery.

    Abstract: A motor driving apparatus makes a carrier signal of an inverter be synchronized with a carrier signal of a DC/DC converter, and determines a phase difference between both the carrier signals based on a ratio of an input voltage inputted to the DC/DC converter and an input voltage inputted to the inverter, and a percentage of modulation and a power factor which are operation parameters of the inverter. When the frequency of the carrier signal of the DC/DC converter is set to be twice as high as that of the carrier signal of the inverter, an optimal phase difference is determined based on the ratio of the input voltage of the DC/DC converter and the input voltage of the inverter.
