Speed variations are obtained by adjusting the electromagnetic torque by controlling the auxiliary winding voltage magnitude and phase angle while the motor's main winding is directly connected to the local utility outlet. A variable auxiliary winding voltage phase angle is shown to yield significant torque control, providing starting and motoring torque as well as reversability and some braking torque. The analysis includes the determination of the relationship between the auxiliary winding voltage phase angle and the phase angle difference between the auxiliary winding currents. A control methodology for selecting an auxiliary winding voltage magnitude and phase angle is examined. Simulation results of the motor's torque-speed characteristics using the controlled auxiliary winding supply are shown and discussed. The drive is tested using a dynamometer to experimentally verify the results of the theory and simulations, and to explore the practicality of a simple, low-cost single-phase induction-motor drive using auxiliary winding voltage control.<<ETX>>","PeriodicalId":274766,"journal":{"name":"Conference Record of the 1988 IEEE Industry Applications Society Annual Meeting","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121853313","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}

Miyao","doi":"10.1109/IAS.1988.25137","DOIUrl":"https://doi.org/10.1109/IAS.1988.25137","url":null,"abstract":"An efficient online PWM (pulsewidth modulation) control method for single-phase full-bridge inverters is proposed. The conventional hysteresis control method has good dynamic responses, but the switching frequencies are high because it does not optimize switching patterns. Full-bridge inverters can generate +E, -E, and 0 (zero) levels where E is an input DC voltage level. The hysteresis control method does not utilize maximum freedom and it selects the output only among two levels (+E and -E). The method selects the optimum output among the three levels (+E, -E, and 0) instantaneously. The control circuit of the proposed method is very simple. Whereas the conventional hysteresis control has only one hysteresis comparator, the proposed method has two hysteresis comparators (wide and narrow loops). When a reference signal goes up, the wide-loop output becomes high and the inverter output is +E, or 0 according to the narrow-loop output. When a reference signal goes down, the wide-loop output becomes low and the inverter output is -E or 0. The method is validated to optimize the output level instantaneously and to reduce the switching times.<<ETX>>","PeriodicalId":274766,"journal":{"name":"Conference Record of the 1988 IEEE Industry Applications Society Annual Meeting","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133051750","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}
