摘要： PROBLEM TO BE SOLVED: To provide a heat-pump type hot water supply device which copes with a request for larger heating capacity without re-designing a component of a heat-pump cycle. SOLUTION: Hot water to be supplied, heated by a plurality of heat-pump cycles 4, is stored in a hot water tank 6. Accordingly, the hot water supply device sufficiently copes with a request for larger heating capacity without designing a new component of the heat-pump cycles 4. Further, as a reference number is set for each heat-pump cycle 4 and the number of operated heat-pump cycles 4 is controlled using the reference numbers, each heat-pump cycle 4 can be made to recognize the reference number of its own even if the heat-pump cycles 4 are produced collectively. Accordingly, a necessary number of heat- pump cycles 4 can be operated whenever necessary, and as a result, the heating capacity of the system on the whole is efficiently controlled.

摘要： PROBLEM TO BE SOLVED: To improve element stability, while suppressing a decrease in output performance by restricting the temperature of a semiconductor switching element to be less than a predetermined temperature by increasing the decreasing speed of current, when a temperature changing speed near the semiconductor switching element is high in the rising direction. SOLUTION: A control voltage is applied to a three-phase inverter circuit 2 by a controller 3, a temperature sensor 5 is fixed near a semiconductor switching element of the three-phase inverter circuit 2, and the sensor is cooled by cooling air. When the temperature detected by the temperature sensor 5 is high and the temperature changing rate is high in the rising direction, the revolution changing rate is forcibly reduced down to a low number of revolutions with the maximum decreasing speed. In this way, the element is prevented from exceeding the maximum allowable temperature range, the phenomenon of extensive rise in element temperature is suppressed, and superior element protection effects can be achieved.

摘要： PROBLEM TO BE SOLVED: To enable the switching from operation controlled by others to a self-controlled operation without fail, regardless of the existence of the components of rotating pulsation.
SOLUTION: At switching from others-controlled operation being performed by applying specified frequency of application voltage to the winding of an armature to self-controlled operation whose phase is controlled, based on the position detection signal, the phase differences between the actual phases obtained based on the position signal and the phases of application voltage are sampled for a period equivalent to the last one revolution of the motor (S1). Then, if it is in leading phase condition where the phase of the application voltage advances by a specified value or over, this controller decreases (S6) the duty ratio of the application voltage, and in addition if it is in a delay phase condition where the phase of the application voltage is delayed for a specified value or more from the actual phase, this increases (S10) the duty ratio of the application voltage, and when all of each phase difference signal detected for a specified period are contained in the specified phase difference range (S4), and when a part of each phase difference signal detected for a specified period is contained in the specified phase difference range and that the remainder of each phase difference signal advances is in a leading phase condition (S9), this the switching is performed (S11).

摘要： PROBLEM TO BE SOLVED: To produce an excellent output current boosting effect with a simple structure without lowering the element safety. SOLUTION: A power module 110 in which a semiconductor switching element chip 112 for electric power is fixed on a heat-radiation/heat-sink metal block 111 is placed at an outside-air current flowing portion of a vehicle so as to be cooled down by the outside-air current through a cooling member 14. The power module 110 is designed to have an increased current limit value when the vehicle speed is large and to have a decreased current limit value when the vehicle speed is small. This simplified structure can achieve an excellent output current boosting effect without lowering the element safety.

摘要： PROBLEM TO BE SOLVED: To prevent the frost of an evaporator without generating the sudden temperature fluctuation of blowoff air into a cabin by controlling the rotating speed of a compressor so that the temperature detected by an evaportor temperature detecting means becomes the target blowoff temperature when the target blowoff temperature is higher or lower than the set temperature. SOLUTION: Whether the temperature of an interior heat exchanger should be lowered or heightened is judged by judging whether or not the temperature after evaporator (Te) is the set temperature in a cabin or more. Since the temperature of the interior heat exchanger 14 is to be lowered in the case of being judged affirmative and heightened in the case of being judged negative, an inverter 19 is controlled so as to attain Te=TAO on the basis of the target blowoff temperature (TAO)-Te and the change rate of Te, to maintain, increase or reduce the rotating speed of a compressor 10.

摘要： PROBLEM TO BE SOLVED: To provide a driving device for multiple-battery electric automobile which hardly causes an inoperable state due to insufficient charging of a low- voltage battery and, in addition, can remarkably reduce the switching noise voltage superposed upon a low-voltage power line on the side of a battery for auxiliary device. SOLUTION: A driving device is provided with a high-voltage battery 1 for supplying power to a running motor 4, a low-voltage battery 2 for supplying power to auxiliary devices, a three-phase inverter circuit 31 which is supplied with power from the battery 1 through a shielded high-voltage side power line 5 and controls the drive of the running motor 4, and a driver circuit 32 which intermittently controls the inverter circuit 31. In this constitution, the driver circuit 32 is supplied with power from the battery 1 through the shielded power line 5. When the driving device is constituted in such a way, the large switching noise voltage of the inverter circuit 31 can be prevented from flowing in a low-voltage power line 7, through which power is supplied to auxiliary devices including electronic equipment such as the radio, etc.
