    • A dehumidifying apparatus with an electronic refrigeration unit includes a thermoelectric unit, a DC power source, and absorbing and liberating heat exchangers. The thermoelectric unit includes a plurality of N-type thermoelectric elements, heat absorbing electrodes, P-type thermoelectric elements, and heat liberating electrodes electrically connected in series. The DC power source supplies DC current to the N-type and P-type thermoelectric elements serially connected through the heat absorbing and heat liberating electrodes. The absorbing and liberating heat exchanger are integrated with the heat absorbing and liberating electrodes, respectively. A heat liberating surface of the liberating heat exchanger is formed at a position different from the absorbing heat exchanger. The absorbing and liberating heat exchangers include heat absorbing and liberating fins, respectively. A notch is formed in one side of each of the heat liberating fins so that a part of a heat absorbing fin fits the notch. The heat absorbing fins are set in a position corresponding to a notch of a corresponding heat liberating fin so that a part of the heat absorbing fin overlaps a part of the heat liberating fin. The overlapped portions are used for the heat absorbing and heat liberating electrodes.

    • A thermoelectric transducer apparatus comprises a group of thermoelectric elements having N-type elements and P-type elements alternately arranged in a single line and a number of alternately arranged heat-absorbing-type and heat-liberating-type plate electrodes to electrically and serially connect said N- and P-type elements. Each of said heat-absorbing-type plate electrodes is extended to form a pair of integral heat-absorbing heat exchanger plates projecting in a direction from said group of elements, said pair of heat-absorbing heat exchanger plates having a pair of first plane areas extending in parallel with the group of elements and oppositely from each other and a pair of second plane areas extending from the respective first plane areas to leave the groups of elements, the outer surface of each of said second plane areas of each heat-absorbing heat exchanger plate being respectively bonded to the adjacent second plane areas of the neighboring heat-absorbing heat exchanger plates by means of insulating adhesive agent. Each of said heat-liberating-type plate electrodes has a pair of first plane areas and a pair of second plane areas all similar to those of each heat-absorbing p-type plate electrode. First and second partition walls for separating the cooled and coolant fluids of the thermoelectric transducer apparatus are formed by serially connecting the first plane areas of said heat-absorbing heat exchanger plates and those of said heat-liberating heat exchanger plates.

    • When performing PWM control in accordance with an overmodulation mode, an ECU variably sets a switching determination value, which is used for determination of switching control modes between the overmodulation mode and a sinusoidal wave modulation mode, based on a switching state of an inverter at present. Then, the ECU compares the degree of modulation, which is calculated from voltage command values, with the switching determination value so as to determine whether to switch to the sinusoidal wave modulation mode or to maintain the overmodulation mode. In particular, when an influence of a dead time is likely to cause generation of a voltage command that requires switching to the overmodulation mode just after switching to the sinusoidal wave modulation mode, the switching determination value is variably set to prevent the transition from the overmodulation mode to the sinusoidal wave modulation mode. This prevents chattering in which the control modes are frequently switched therebetween.
    • 当根据过调制模式执行PWM控制时,ECU基于目前的逆变器的开关状态可变地设置用于确定过调制模式和正弦波调制模式之间的开关控制模式的开关判定值 。 然后,ECU将根据电压指令值计算的调制度与切换判定值进行比较,以便确定是切换到正弦波调制模式还是维持过调制模式。 特别地,当切换到正弦波调制模式之后,当死区时间的影响可能导致产生需要切换到过调制模式的电压指令时,切换判定值被可变地设置以防止过调制 模式到正弦波调制模式。 这防止其间经常切换控制模式的抖动。
