Traditional DC-DC Boost converters are used in high voltage applications, but they are not economical due to limited output voltage, large voltage ripples, current ripples and power losses. A closed loop control scheme for a simple DC-DC Boost converter in designed and the performance characteristics are studied using MATLAB simulink. The performance of the controller is also studied for variou...

This paper introduces a versatile control scheme for unidirectional ac–dc boost converters using fuzzy logic controller for the purpose of mitigating grid power quality. Since most power factor correction circuits available in the commercial market utilize unidirectional ac– dc boost converter topologies, this is an almost nocost solution for compensating harmonic current and reactive power in ...

This paper presents a single-phase five-level photovoltaic (PV) inverter topology for grid-connected PV systems with a Sinusoidal Pulse Width-Modulated (SPWM) control scheme. The photo-voltaic arrays are connected to fivelevel multilevel inverter through the DC-DC boost converter. By implementing maximum power point tracking algorithm are producing more power from PV array. The DC power from th...

This project is a highly efficient and novel control strategy for improving the transients in the output voltage of a dc–dc positive buck–boost converter which is required for low-power portable electronic applications. The proposed control technique can regulate the output voltage for variable input voltage (higher, lower, or equal to the output voltage). There are several existing solutions t...

Multichannel resonant DC/DC converters have recently been popular in diverse fields, where multiple output voltage levels are required, such as supplying multilevel inverters. This paper is devoted to present the new member of a four-channel converter family, having consisted till now step down well step-up/down configurations. The capable realizing power flow amongst two input and four channel...

DC-based therapeutic vaccines as a promising strategy against chronic infections and cancer have been validated in several clinical trials. However, DC-based vaccines are complex and require many in vitro manipulations, which makes this a personalized and expensive therapeutic approach. In contrast, DNA-based vaccines have many practical advantages including simplicity, low cost of manufacturin...
