Traditional silicon binary circuits continue to face major challenges such as high leakage power dissipation and high area of interconnections. Multiple-Valued Logic (MVL) and nano-devices are two feasible solutions to overcome these problems. In this paper, a novel method is presented to design ternary logic circuits based on Carbon Nanotube Field Effect Transistors (CNFETs). The proposed designs...
Most recently, the major proportion of transporta-tion sector utilizes fossil fuels. Burning of fossil fuels adds massive amount of carbon in the atmosphere. Moreover, the fossil fuels reserves are depleting and their prices are also fluctuating. In addition, new environmental policies are also being made to reduce carbon emissions. So, electrification of the transportation sector is essential to...
The latest development of 5 kW Transformerless Bidirectional Inverter in PT. Len Industri is reported, accompanied with the experimental result. The dc-dc converter and inverter topology and control is described in brief. Next, hardware design and parallel design are examined. Parallel operation component will be highlighted, such as PLL, Droop Control and Virtual Impedance. Finally, the inverter...
The development of transformerless 5 kW grid connected/offline bidirectional inverter simulation in PT. Len Industri is reported. The aim of transformerless is to reduce total cost and losses; making it more suitable for remote area application. The bidirectional inverter consist of two stage: bi-directional multiphase dc - dc converter and single phase inverter. Double PI control loop is used in...
Development of Len Bi-directional Inverter 15 kW (LenBDI15K-1P) and Len Battery Solar Charger 65 A (LenBSC65A-240V-BO) will be presented in this paper. These two products are used as power converter for 15kW solar off-grid power plant. The bi-directional inverter is using single phase full-bridge topology with a PI controller for inductor current and unbalanced d-q frame controller for voltage output...
The paper presents field oriented control of a five-phase induction motor drive system. The five-phase induction motor is supplied from a current controlled five-phase voltage source inverter and the inverter is supplied from a three-phase active front end converter. The novelty of the paper lies in the development of the five-phase drive with the active front converter. The front end converter has...
The paper presents AC/DC/AC power electronic converter system with five-phase two-level active rectifier and five-phase two-level inverter with a dc link. Five-phase active rectifier system is presented for the first time in this paper. This is an extension of a three-phase active rectifier with two additional legs. This topology may find its application in five-phase variable speed generator such...
