DC-DC boost converters are mostly employed in renewable energy system such as photovoltaic system, fuel cell and so on, because these systems generate low output voltage which is not suitable for grid connected power applications. This paper proposes an interleaved boost converter which consists of voltage doubler cell and clamped circuit to achieve large output voltage gain without extremely i...
in this paper, a low voltage and low power (lv/lp) operational transconductance amplifier (ota) using fgmos (floating-gate mos) transistor is proposed. the relative tuning range of 50 is achieved in this ota while only consumes 40 µw with 1.0 v supply voltage in tsmc 0.18 µm cmos technology. the simulation results of the proposed ota show an open loop gain of 30.2 db and a unity gain frequency ...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
A low to high voltage conversion technique has been proposed in this paper using double stages of switched inductors for nanogrid applications. The converter topology utilizes fewer components, achieves gain at a small value duty ratio, and efficiency. Moreover, the provides reduced switch current stress obtain stable constant boosted DC voltage. Therefore, it requires low-current rating switch...
In this paper, a simple control method is presented for a single-stage single-switch isolated power-factor-correction (PFC) regulator that can simultaneously achieve unity power factor and fast output voltage regulation while keeping the voltage stress of the storage capacitor low. The converter topology comprises essentially a cascade combination of a discontinuous-mode boost converter and a c...
This paper presents a new design of zero-voltage-switching (ZVS) buck converter. This new converter utilizes a coupled inductor to implement the output filter inductor as well as the auxiliary inductor which is commonly employed to realize ZVS for switches. Additional magnetic core for the auxiliary inductor in traditional designs is removed and hence manufacture cost is reduced. Moreover, than...
This paper focuses on the study of DC-to-DC converters, which are suitable for low-voltage high-power applications. The output voltages generated by renewable energy sources such as photovoltaic arrays and fuel cell stacks are generally low and required to be increased to high voltage levels. Development of DC-to-DC converters, which provide high step-up voltage conversion ratios with high effi...
Voltage references are crucial part of every circuit, providing a fixed voltage regardless of environmental parameters and device loading. Among several approaches proposed for designing voltage references, bandgap voltage references are the most common, but the bandgap voltage reference is bipolar in nature and does not show good stability when the supply voltage is small. Thus according to th...
In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...
