This paper proposes a new high step-up DC–DC converter designed especially for regulating the dc interface between various micro sources and a dc–ac inverter to electricity grid. The need of Electricity increases the power demand where the power demand met by the conventional sources of energy has some disadvantage of pollution, this disadvantage can be decreased by the use of the Renewable ene...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

Low power efficiency is one of the main problems THz sources, colloquially known as gap. In this work we present prototypes devices based on whisker-crystals a hightemperature superconductor Bi2Sr2CaCu2O8+d with record high radiation 12% at frequency 4 THz. We employ various on- and off-chip detection techniques and, in particular, use radiative cooling phenomenon for accurate evaluation emissi...
