This paper presents a study on recent developments in dc-dc converters. All the converters are derived based on the two basic converters such as buck converter and boost converter. The aims of developing the converters are high efficiency and high gain with fast response. Today’s world demands the low power application devices which is the focus of the researchers. There are so many parameters ...

On 30 June 2022, the IEEE Power Electronics Society (PELS) Student Branch Chapter (SBC) at Vimal Jyothi Engineering College (VJEC) organized a Regional Distinguished Lecture (RDL) program with topic “High Converters Contributing Grid Stabilization in Japan.” The lecture was presented by Senior Fellow Dr. Noriko Kawakami of Toshiba Mitsubishi-Electric Industrial Systems Corporation.

This paper presents a modulation extension control algorithm for hybrid cascaded H-bridge multilevel converters. The hybrid cascaded H-bridge multilevel motor drive using only a single dc source for each phase is promising for high-power motor drive applications since it can greatly decrease the number of required dc power supplies, has high-quality output power because of its high number of ou...

Based on the proposed silicon integrated power transistor adopting a 0.18 lm technology, its performance shows this novel device can be operated at 2.4 GHz for Bluetooth and lithium battery applications [Hsu H-M, Su J-G, Chen C-W, Tang DD, Chen CH, Sun JY-C. Integrated power transistor in 0.18 lm CMOS technology for RF system-on-chip applications. IEEE Trans Microwave Theory Tech 2002;50(Decemb...

this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

For multi-objective optimal reactive power dispatch (MORPD), a new approach is proposed where simultaneous minimization of the active power transmission loss, the bus voltage deviation and the voltage stability index of a power system are achieved. Optimal settings of continuous and discrete control variables (e.g. generator voltages, tap positions of tap changing transformers and the number of...

This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...
