Abstract:

This paper presents a new type diode connected MOS transistor to improve CMOS conventional rectifier's performance in RF energy harvester systems for wireless sensor networks in which the circuits are designed in 0.18 μm TSMC CMOS technology. The proposed diode connected MOS transistor uses a new bulk connection which leads to reduction in the threshold voltage and leakage current; therefore, it contributes to increment of the rectifier’s output voltage, output current, and efficiency when it is well important in the conventional CMOS rectifiers. The design technique for the rectifiers is expl

Abstract:

The article discusses the problem of transformation of measuring signal of differential transformer converter of universal testing machines for further processing by microprocessor controller. In order to automate the testing process, it is necessary to collect, process and transmit the measured data to an automated workplace using a microprocessor controller. Due to the fact that usually the secondary windings of the differential transformer converters produce an alternating voltage of very small magnitude, such a measurement signal cannot be processed with the help of modern microprocessor c

Abstract:

This paper pursued both the lower operating power limit and small area of on-chip rectifiers for microwave wireless power transfer (MWPT). RF–DC charge pump rectifiers can operate in the fast switching limit at a high frequency of 920 MHz even with a small stage capacitor Cin of 100 fF, which contributes to an area reduction in the on-chip rectifiers. Circuit design starts with Cin determined as small as possible, followed by the determination of switching transistors and the number of stages. Even at an extremely low input power of 1 μW, wiring resistance in RF inputs is critical. Routing of

Forward and reverse bias performance of 10kV, 10A and 20A junction barrier-controlled Schottky 4H silicon carbide rectifiers are presented. Over a temperature range of 30 to 200°C, the forward current-voltage curves show a normal Schottky rectifier relationship and the reverse current-voltage curves show typical PiN blocking. When operated in reverse-blocking at 125°C and 8kV, the 10A JBS rectifiers are notably stable at less than 5μA of leakage current, despite the large active area of the devices.

Abstract:

In many switching power supply converters, diode rectifiers are used to obtain the DC output voltage. The conduction loss of these diodes rectifier contributes significantly to the overall power loss, especially for low-voltage, high-current converter applications. The conduction loss of rectifying diode is given by the product of its forward-voltage drop and forward conduction current. By replacing the diode rectifiers with a MOSFET operating as a synchronous rectifier (SR), the equivalent forward-voltage drop can be lowered and, consequently, the conduction loss can be reduced because the sw

The paper presents a proposal of the multi-pulse AC/DC converter for providing supply for multilevel inverters and considerably reducing the line current distortion factor. It can be applied as a suitable source of DC voltage and is convenient to supply such inverters that need three or more voltage terminals to supply all sections of the inverter. The converter in question works as a multi-pulse rectifier supplying a three-level NPC (Neutral Point Clamped) inverter. The load introduced by the inverter is simulated as an impedance depended on a selected inverter state. All possible states are

Its novelty is in the use of optimal-length transmission lines on the load side of the 4 half-wave rectifying stages within the two-stage voltage multiplier topology. Doing so boosts the rectifier's output voltage due to an induced standing-wave peak at each diode's input, and gives the rectifier a 50 Ω input-impedance without an external-matching-network in the 2.4 GH
