Various kinds of current-source inverter circuits h ave been discussed aiming a t improving the output an d input voltage and current waveforms . Their PWM control methods and stability analysi s for i nduction motor drive have also been " discussed [1][2][3][4][5][6] . Earlier, the present authors discussed a lso the steadysta te characteris t ics (e.g., efficiency, power fac t or, torque, etc.) of the induction motor driven by the c urrent-sour ce i nverter [7] .The waveforms of instantaneous voltages and currents ha ve also been a na lyzed by the state eq ua t ion method [8]. Th is paper proposes a new method t o ana l yze the waveforms of insta nt a neous voltages and currents. In this method, the ha rmon ic components of output voltage a nd current wa veforms a re analyzed using a n equivalent circuit a nd they are s ynthesized . The validity of the proposed method is confirmed by comparison with the measured results. The proposed method has ma ny features as described in the following:(1) the equivalent circuit of the induction motor is used; (2) the calculation procedure is simple; a nd (3) not only the volt age and current waveforms but a ls o the distortion factors, ha rmonic contents, total efficiency and power factor of induction motor can be obtained. In the proposed circuit, condensers are connected a t the output terminals and they opera te as the output filter . The resonance caused by the output condensers and motor leakage inductances is taken into account using an equival ent circuit of the induction motor. The effects of switching frequency and output condenser capacity on the output voltage and current waveforms and distortion factors are analyzed. The analyzed results are compared wi th the measured ones. . Ci rcuit Configura tion and Basic OperationThe main circuit configuration discussed in this paper is shown in Fig. 1.
