Most schemes need some calculations to estimate the power line voltage using circuit parameters. In this paper, we propose a novel control strategy of the three phase PWM converter by tracking control of the operating frequency based on the power balance of the converter. The system is composed of the direct PWM control loop of the instantaneous active and reactive current. The features of the proposed PWM control system are simplicity without sensing the line voltage, high reliability with poor dependence of the circuit parameters, high efficiency and fast response etc.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130299425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it becomes important, when the inner states of the load connected to the inverter has to be calculated using the quantities of the load terminal voltages and currents, such as in the case of vector control of the induction motor without speed sensor. This paper tries to give an accurate measuring method for it. The voltage cluster from the inverter is integrated every half period of the switching. Then the output of the integrator will be reset to zero after its volt-second value has been detected digitally. Two groups of the circuit take the alternative operation. High accuracy and linearity of the measurement can be achieved. The measurement of the instantaneous current has also been discussed.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130247314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The output voltage ripple from input power unbalances-especially caused by a single line-to-ground fault (SLGF)-is analyzed to represent the amplitude of the ripple with some given parameters. This paper also shows that some converters' operation can be unstable when using a synchronous frame controller by unbalanced input power resulted from a SLGF. The authors discuss a method that makes the power converter run within a certain voltage ripple boundary even under faulted power conditions. Finally, the operation of the discussed power converter is simulated and experimented upon in order to verify the results.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128467855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The input current waveform in the proposed circuit is of a discontinuous sinusoidal form in proportion to magnitude of the AC input voltage under constant duty cycle switching. Thereupon, the input power factor is nearly unity and its control circuit is simple. Also the switching devices in the proposed circuit are operated with soft switching using the partial resonant method. The result is that the switching loss is very low and the efficiency of the system is high. The partial resonant circuit makes use of a inductor using step up and L/sup 2/SC (lossless snubber condenser). The switching control technique of the power converter is simplified for the switches to drive in a constant duty cycle. Some computer simulation and experimental results are included to confirm the validity of the analytical results.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122760867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first one the field oriented control method is used to control the speed of the induction motor. In this system the spatial vector of the stator current is transformed into a i/sub 1q/ component which creates the torque, and into a i/sub 1d/ component which creates the flux. If d-axis component of the stator current is of constant value, the motor drives with a constant flux and the torque can be altered rapidly by means of the q-axis component of the stator current i/sub 1q/. Two components U/sub 1d/, U/sub 1q/ of stator voltages in d-q coordinate system which must be applied to the stator d-q equivalent windings, are generated by two PI regulators controlling the two components: flux-generating and torque generating stator current. In the second one the stator flux oriented control method is used to control the torque of the induction motor. By using instantaneous voltage space vectors with selection of optimum inverter switching modes employing vector modulation technique, the direct control of torque and stator flux is achieved.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127680716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
