摘要： An ultra low cost electric vehicle heating apparatus, components thereof, and related method are herein described. A driver circuit operates a switching device at an intermediate state between fully-turned-off and fully-turned-on, in a high power dissipation heating mode, to efficiently produce heat energy for heating a passenger compartment, or energy storage system, of an electric vehicle. The driver circuit operates the switching device to have a fully-turned-off state and a fully-turned-on state in a main function mode for a traction inverter or an energy storage system charger of the electric vehicle. The driver circuit is operable to cycle the heating mode and the main function mode for combining such heating and such main function operation of the traction inverter, or the charger, without compromising the operation of the traction motor, or charger, while simultaneously eliminating many of the expensive resistive heating components in use by practitioners of the art.

摘要： A hybrid vehicle includes an engine in which a particulate matter removing filter configured to remove particulate matter is disposed in an exhaust system; a motor configured to receive and output power; a driving circuit configured to drive the motor; an electric power storage device that is connected to the driving circuit; and a control unit configured to control the engine and the driving circuit. The control unit is configured, when a high temperature request for increasing a temperature of the particulate matter removing filter to a prescribed value or higher is issued, to control the driving circuit such that a loss of the driving circuit increases and to control the engine such that power greater than power at a time when the high temperature request is not issued is output from the engine.

摘要： A vehicle includes an inverter, a motor, a transmission, and a modulator. The inverter performs pulse width modulation processing at a predetermined carrier frequency. The motor is supplied with electric power from the inverter. The transmission changes the number of revolutions of the motor, and transmits rotary power of the motor to one or more driving wheels. The modulator controls the pulse width modulation processing performed by the inverter, and changes the carrier frequency of the pulse width modulation processing, to offset a change in a frequency of a sideband component out of frequencies of a carrier sound. The carrier sound is generated in the motor or the inverter, or both, accompanying a stepwise change in the number of revolutions of the motor on a condition that the stepwise change is made by the transmission.
