Factors contributing to a motor overvoltage transient equal to twice the theoretical DC bus voltage are described using classical transmission line analysis. A critical cable distance (I/sub c/) is defined where twice the DC bus overvoltage occurs. However, literature is lacking on how motor transients greater than twice the DC bus voltage are generated. This phenomenon is observed on all PWM inverters with output cable lengths greater than the I/sub c/ distance. Theoretical calculations of cable frequency and damping are correlated with simulation and experimental results. Finally, the paper presents an external hardware apparatus (the Terminator), based on a cable's characteristic impedance, that clamps the motor's terminal voltage to levels far below twice the DC bus voltage. All calculations and proposed solutions are verified or demonstrated with experimental results.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116253712","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}

It obtains one cycle response by forcing the error between the switched-variable and the control reference to zero, each cycle. The on-pulse of the controller is adjusted each cycle by a simple circuit to ensure almost constant switching frequency. The small switching frequency variation due to variations in the reference signal and supply voltage and delays in the circuit are quantified. An additional improvement is achieved by using double edge modulation. An experimental 10 kHz bandwidth 100 Watt RMS power audio amplifier using the control method shows THD+N less than 0.62% and power supply ripple rejection (PSRR) of 56 dB demonstrating the applicability of this control technique for high fidelity audio applications.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116566779","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}

It is shown here that torque pulsations due to the rotor perturbation can be eliminated by modulation of the input motor current based on flux identification determined by a neural network.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115228028","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 proposed system consists of an autotransformer (0.18 P/sub a/), two diode/SCR rectifier bridges and a new active interphase transformer. The new active interphase transformer combines the function of two zero sequence blocking transformers (ZSBT), and a conventional interphase transformer into one component wound on the same core. Further, an additional auxiliary winding is added on to the same core to facilitate active current shaping or input current for clean input power. A low kVA two-switch PWM-VSI is employed to control the auxiliary winding current to realize near sinusoidal utility line currents under varying load condition. The proposed system is suitable for the utility interface of high power AC motor drive systems to meet the current IEEE-519 harmonic current limits. The proposed system is very rugged and, in the event the active control were to fail, the system reverts to 12-pulse operation with 5th and 7th harmonics cancellation. Further the active PWM unit is of low kVA (0.15P/sub 0/) and is not directly exposed to line transients. Analysis and design of the proposed system is examined in detail and simulation results are shown.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116851452","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}
