Abstract: A power converter includes: a conversion circuit for conversion between DC power and N-phase AC power (N33); and a control unit controlling 2N switches. The control unit periodically switches between a first PWM mode in which a high-side or a low-side switch of one phase among the 2N switches is turned on and the switches of the remaining phases are controlled by PWM, and a second PWM mode in which the switches of all phases among the 2N switches are controlled by PWM. The sum of the first period of the first PWM mode and the second period of the second PWM mode is shorter than 1/2N of one electrical angle cycle of the AC waveform of the AC power. The first period is equal to or longer than one cycle of PWM. The ratio of the first period to the sum of the first and second periods is variable.

Abstract: A motor control device includes a conversion circuit that is connected to an n-phase motor, and a control unit that controls the conversion circuit based on n-phase duty command values updated at a predetermined update cycle. When the control unit predicts, based on the n-phase duty command values, that voltage fluctuations of at least two-phase connection terminals among the n-phase connection terminals connected to the n-phase motor occur in the same direction and at the same timing, the control unit delays the occurrence timing of the voltage fluctuation of one of the two-phase connection terminals by a first time and advances the occurrence timing of the voltage fluctuation of another connection terminal by a second time. The total value of the first time and the second time is a predetermined time during which predetermined occurrence timings of the voltage fluctuations of the two-phase connection terminals do not overlap each other.

Abstract: A motor control device includes an inverter circuit to convert a DC power source voltage into a three-phase AC voltage and supply the three-phase AC voltage to the three-phase motor and a controller to generate three-phase PWM signals based on three-phase duty command values updated at a predetermined updating cycle and control the inverter circuit based on the three-phase PWM signals. The controller is configured or programmed to shift, when duty command values of at least two phases of the three-phase duty command values updated at a first update timing are the same, the duty command value of one phase of the duty command values of the two phases by a predetermined shift amount and shifts a duty command value of the one phase of the three-phase duty command values updated at a second update timing which is an update timing next to the first update timing by the shift amount in a direction opposite to a shift direction at the first update timing.

Abstract: A power conversion device converts DC power into n-phase AC power. A first voltage and a second voltage lower than the first voltage are applied to the power conversion device, and the power conversion device outputs an n-phase output voltage based on a modulation factor. n is the number of phases of the AC output, and is an odd number of 3 or more. At a low modulation factor equal to or less than a first modulation factor, the output voltage becomes a sinusoidal output. At the second modulation factor larger than the first modulation factor, the output voltage is switched every electrical angle ?/n between the phase in which the output voltage is fixed to the maximum voltage and the phase in which the output voltage is fixed to the minimum voltage.

Abstract: An inverter circuit includes at least three output terminals, a first input terminal, a second input terminal, and at least three series bodies. A total switching duration and a one-phase fixed duration are present within a single cycle of AC output. The waveform of each phase of an output voltage is such that a shared offset wave is deducted from a sinusoidal waveform. The waveform of the offset wave matches one phase of the sinusoidal waveform, or matches a waveform obtained by shifting the one phase of the sinusoidal waveform in the amplitude direction, during the one-phase fixed duration. During switching between the total switching duration and the one-phase fixed duration, the inclination of the waveform of the offset wave either continuously changes or remains fixed.

The receiving portions are configured to have different insertion allowances for the opposing electrodes, respectively, according to the tip shape of each of the pair of opposing electrodes.
