Although the spectral modifications that are associated with chaotic operation may provide an important motivation for actual operation in this regime, the literature on chaos in power electronics has tended to treat it more as an exotic effect than as a feasible mode of operation. This may explain why no prior work has attempted-for the chaotic regime-to characterize even the most basic property of DC-DC power converters, namely the input-output gain (which is the ratio of the average output voltage to the DC input voltage). The present paper shows how to compute this gain, and other averages of interest, for the chaotic regime of buck, boost, and buck-boost power converters under constant-frequency current-mode control and in continuous conduction. The authors' approach invokes the fact that the chaotic sampled inductor current is ergodic, hence governed by a \"probability\" density, which permits time averages to be replaced by ensemble averages. Although the density can be computed in detail, it turns out that approximating it (quite crudely) as a uniform density still yields very good results. In contrast, traditional computations based on the nominal (and unstable) periodic solution can be considerably in error.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"83 1","pages":"1477-1483 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84252197","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}

Depending how the integrator is used, the dynamic performance differs greatly. This paper presents a systematic evaluation of the function of integrators in some representative integrator related PWM methods, such as ASDTIC control, delta/delta-sigma modulation, modulated integral control and one-cycle control. In general, zero steady-state error is granted for all methods. Further, the variable frequency control methods are able to achieve one-cycle dynamic response. In the constant frequency category, however, only the one-cycle control method achieves one-cycle dynamic response, i.e., it realizes zero dynamic tracking error in the cycle average sense. In this paper, performance enhancement rules were explored for variable frequency control method in order to reduce the frequency variation. For the one-cycle control method, a pulse position modulation effect is identified which deteriorates the perturbation rejection ability of the single-side modulated one-cycle control method in the high frequency range. As a result, a double-side modulation is proposed that effectively reduces this effect. In addition, a fast reset mechanism is suggested that improves the switching error correction. This paper also provides a general approach to use integrators in PWM to realize arbitrary function.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"6 1","pages":"773-781 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79449810","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}

This approach is based on the fact that the time of appearance of a voltage pulse traveling on a channel is directly proportional to the electrical length of the channel. Thus, if power pulses are fed into the inputs of a group of transmission lines sequentially, they may reach the end points simultaneously, if certain measures are taken. The first pulse should be applied to the input terminals of the longest transmission line, the second to the next, shorter transmission line and so on, the last pulse in the cycle is fed into the shortest transmission line. If the system is composed of m transmission line segments, the difference in the electrical length from line to line should be T/m, where T denotes the period of the cycle. The output peak power will be m times higher than the input peak power, due to either a rise in voltage, in current, or a combination of both. The current/voltage magnification would be defined by the choice of a suitable connection mode at the end points. The main advantages of the transmission line based topology are: (a) the switching elements the system consists of need to withstand a much lower power than the power experienced by the load, and (b) the system can operate either at extremely high frequencies or with very short rise and decay times of rectangular pulses.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"85 1","pages":"1323-1328 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80663296","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}
