    Abstract: A motor-driven compressor includes a three-phase motor including a rotor, a housing, a compression unit, a drive circuit, and a controller. The drive circuit includes u-phase upper and lower arm switching elements, v-phase upper and lower arm switching elements, and w-phase upper and lower arm switching elements. The controller performs a deceleration control in response to the rotor being rotating in a direction opposite to the forward direction. The controller controls the drive circuit in a switching control mode that includes a first mode, in which one or more switching elements of the upper and lower arm switching elements of the three phases are activated while the remaining switching elements are deactivated, and a second mode, which differs from the first mode in a combination of the activated and deactivated switching elements.

    Abstract: A method for regulating the temperature at an outlet channel of a compressor or a vacuum element, comprising providing a pressure regulating valve on a influence channel, said influence channel being in direct fluid communication with the compressor or vacuum element, said valve regulating the pressure within the compressor or vacuum element by adjusting the volume of fluid flowing between a process channel and the compressor or vacuum element relative to the difference between the pressure value within said compressor or vacuum element and a set pressure value, and comprises starting the compressor or vacuum element and starting a pre-purge cycle by connecting the inlet channel to a supply of a purge gas for a preselected time interval; connecting the influence channel to a process channel; and disconnecting the inlet channel from the process channel, for maintaining a set temperature within the vacuum element for a selected time interval.

    Abstract: A motor-driven compressor is provided with a motor including a rotor, a housing including an inlet through which low-pressure refrigerant serving as a low-pressure fluid is drawn in, a compression unit that compresses the low-pressure refrigerant and discharges compressed high-pressure fluid, an inverter that drives the motor, and a controller that controls the inverter. If the rotor is activating in a reverse direction that is opposite to a forward direction when activating the motor, the controller obtains a position of a d-axis of the rotor and controls the inverter so that current flows to the obtained d-axis and so that frequency of current flowing to the motor decreases as time elapses.

    Abstract: Provided are a circuit assembly including a circuit component fixing structure capable of preventing damage to a fixing portion and a connection terminal caused by vibrations, and a vehicular electric compressor. The circuit assembly includes: a circuit board; a circuit component connected to the circuit board; and a circuit casing housing both the circuit board and the circuit component. The circuit component includes a component body disposed facing the circuit board inside the circuit casing, a connection terminal directly fixed to the circuit board, and a first fixing portion and a second fixing portion that are fixed to the circuit casing around the component body. In a direction orthogonal to the circuit board, the first fixing portion is positioned on a side of the circuit board with respect to the center of gravity of the circuit component, and the second fixing portion is positioned on a side away from the circuit board with respect to the center of gravity.
