    摘要： An inverter apparatus for converting a DC power converted from an input AC power to an output AC power of a variable frequency and a variable electric power to drive an induction motor at a variable speed. The inverter apparatus includes a rectifying unit, a filter capacitor, an inverter unit having an input connected across the filter capacitor, an input current detector and a gate circuitry for driving the inverter unit. An excitation current detection unit detects an excitation current of the induction motor from an output signal of the input current detector, a gate signal for driving the gate circuitry and a reference phase command. A setting unit sets a limitation level of the excitation current, a torque boost voltage command unit produces a torque boost voltage command, and a torque boost voltage compensation unit changes the torque boost voltage command so that the detected excitation current value is smaller than or equal to the limitation level.

    摘要： Induction voltage command Em* is obtained from inverter's primary frequency command &ohgr;1* and torque boost voltage commander produces torque boost voltage command &Dgr;Vz* in accordance with &ohgr;1* while integrator produces reference phase command &thgr;d*. uvw/dq converter detects motor excitation current Id (equivalent of no-load current). Next, deviation of excitation current limitation level command Idmax* and detected Id is inputted to limiter processing unit to produce torque boost voltage compensation value &Dgr;Vc for varying &Dgr;Vz* so that Id is smaller than or equal to Idmax*. Inverted &Dgr;Vz* is set up as a lower limiter value of the limiter processing unit. Next, &Dgr;Vc and &Dgr;Vz* are added to produce final compensated torque boost voltage command &Dgr;Vt* and &Dgr;Vt* and Em* are added to produce q-axis voltage command Vq* of the inverter output voltage.

    摘要： In order to bring a moduled power converter into less size and cost in the case of a structure having a lead-insert-case, an insulated metal circuit board and a printed circuit board, a difficulty was encountered in thinning a wiring width and an increase in pad area for each metal wire has interfered with a reduction in its size and cost.In the present invention to cope with it, a power converter is constructed by using a semiconductor module having such a structure that a metal base and lead frames are adhered to each other in a state in which an insulating adhesive sheet is interposed therebetween, a resin-molded outer package is adhered to the metal base with an adhesive or the like, and a resin sealing agent is charged into the resin-molded outer package to thereby integrally seal the resin-molded outer package and circuit parts such as semiconductor elements implemented therein, whereby a reduction in size and cost thereof is realized.
