The converter integrates the operation of a forward converter and a flyback converter. It operates either in the forward mode or the flyback mode depending on whether the input is higher or lower than the reflected output voltage to the transformer primary side. This integrated operation ensures that the dead zone problem of ac input current in conventional forward converters is overcome. It works for the universal ac input range and a high power factor is achieved. The proposed converter operates in critical conduction mode in order to achieve zero voltage switching and constant on-time control is applied. To confirm the validity of the proposed converter, simulations have been done using MATLAB/SIMULINK and are presented here.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"70 1","pages":"109-113"},"PeriodicalIF":0.0,"publicationDate":"2015-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86727305","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 common mode voltage will have adverse effect on the motor bearings. Hence the common mode voltage has to be reduced. This paper presents a modified Sinusoidal Pulse Width Modulation (SPWM) scheme in which two complementary modulating inputs are used to generate the pulses for the switches of a two level, three phase inverter to reduce the common mode voltage. The performance of proposed modulation scheme is evaluated and tested for various switching frequencies. With the proposed modulation scheme the phase voltages appears to be three level voltage which helps in reduction of common mode voltage. A comparative study of common mode voltage with both normal and modified SPWM method is also done and the results are presented in this paper.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"5 1","pages":"244-248"},"PeriodicalIF":0.0,"publicationDate":"2015-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82218542","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}

Solar LED lighting scheme is a major kind of light sources in the coming decades because of the efficiency concerns and renewable energy utilization. Conventional LED driving circuit is the combination of diode bridge rectifier and input PFC stage. Diode bridge rectifier at the front end of driving circuit will cause reduced conversion efficiency and power factor. This paper deals with reliable lighting scheme which can be supplied from both solar panel and conventional supply. A battery storage unit is also used to store the energy from PV panel and it also reduces the peak loading while it charging from conventional supply. The dc supply from grid connection is obtained by using bridgeless flyback converter which has inherent power factor correction capability.

The control schemes employs an outer voltage feedback loop, which maintains the output voltage as constant and an inner loop, which sense the input current. Average and peak current mode control of flyback rectifier is suitable for obtaining a regulated output voltage with a varying input. Voltage equivalent of input current is averaged by using high gain current error amplifier, which again compared with the reference voltage in the case of average current mode control. But in the case of peak current mode control, peak inductor current has been sensed and this gives rise to many serious problems, including poor noise immunity, a need for slope compensation, and peak-to-average current errors which the inherently low current loop gain cannot correct. Reference voltage is produced by multiplying the rectified input voltage with the error output voltage. These control methods obtain better line and load regulation with the addition of inner current loop compared with voltage mode control. Also the rectified input voltage feedback achieves better input power factor. Conventional flyback rectifier is the inter connection of a diode bridge rectifier in the input side and a flyback converter. In order to obtain a highly efficient flyback rectifier with fewer losses an improved flyback rectifier is introduced. Improved bridgeless flyback rectifier only introduces a switch with common gate drive, a diode and an additional winding in the secondary side. Thus the weight of the converter is not affected with these additional components. Proposed peak and average current mode control can be used as an adapter. Design details of average current mode control also discussed and simulation and hardware results are presented.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"10 1","pages":"254-259"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83703745","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 main advantages of space phasor based hysteresis controllers such as fast dynamic response, adjacent voltage vector switching can be seen in the proposed controller. In addition to these, switching frequency variation can be eliminated substantially. The stator voltages estimated from the current ripple, calculation of vector switching times and voltage error vectors are used for the current error boundary calculation. The proposed controller selects only those inverter voltage vectors of the present sector which are adjacent to the machine voltage vectors for the entire range of operation to reduce current error. Bus clamping space vector pulse width modulation(BCSVPWM) is used for vector selection logic where only one zero state is used in a sub cycle of total switching time period.
