From the simulation results of the proposed circuit, the circuit can decrease the THD of the input current compared with the hard switching circuit without the resonant switch. In the soft switching circuit, the DC short circuit occurs more easily and frequently because of the resonant operation. The DC short circuit starts after the switch turns off, and the diode bridge input current in the switch off period is decreased. Then the diode bridge input current in the switch on period increases relatively when the DC short circuit occurs. Therefore the soft switching circuit improves the input current waveform and it becomes sinusoidal. We analyzed and clarified the process and the reason for the input current waveform improvement in the soft switching circuit.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125791644","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 bandwidth of the current regulator is dependent on the switching frequency and digital delay. The limited switching frequency is inevitable to reduce the switching loss due to excessive switching frequency. Also, the digital delay is inherent problem where the Digital Signal Processor (microcontroller) and PWM are used. This paper proposes the novel current regulation strategy to enhance the performance of the current regulation by reducing the digital delay which is the sum of the execution time and PWM delay and modifying the voltage reference. The proposed strategy is robust to the parameter and reference variation. Experimental results are shown to verify the effectiveness of the proposed method.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123437172","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 phenomenon is an original demonstration in the domain of fuel cell research. Naturally, a fuel cell power source is always connected with a power electronic converter (power conditioning circuit) to boost a low dc voltage to a higher utility level. Therefore, to present fuel cell characteristics, a fuel cell power conditioning circuit (classical boost converter) is designed and implemented in the GREEN/INPL laboratory. The studied PEM fuel cell is 500 W, 40 A, around 13 V, designed and manufactured by the ZSW Company. Experimental results authenticate the fuel cell characteristics when the fuel cell power source is operated with a power electronic converter at a switching frequency of 25 kHz. The high switching frequency and significant step load (fuel starvation effect) to the fuel cell voltage and current are clearly illustrated.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131678512","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}
