An Intelligent Power Supply (IPS) can operate on either AC or DC input power. If AC power is available, the system always uses AC power. The power supplies use AC power first and then switch to DC power automatically if AC power fails or is not present. When the AC power returns alive, the DC power source will convert to AC again. Such an IPS will consume less energy and be more cost effective in the industry. The development of an IPS needs a new version of the firmware for a universal interface of SAP (Systems, Applications, and Products) in data processing. The new version needs to provide a programming interface between an IPS and the computer. In this paper, the programming interface, iPort/AFM, is used to connect I2C host adapter with ASCII Fast Mode control. The iPort/AFM works with Windows or non-Windows based host computers. It supports both standard (100Kbps) and fast (400Kbps) Inter-Integrated Circuit (I2C) bus speeds with the I2C Interrupt signal. Controlled with a simple ASCII command interface, this adapter supports RS-232 with baud rates up to 115.2K/sec. It includes a high performance processor for improved throughput with low overhead. Moreover, the proposed interface can be used in DOS, UNIX, SGI, Windows, and Linux. The end product in industrial applications includes an adapter unit, software, cables, and a global power supply
Multiplication Algorithms have considerable effect on processors’ performance. Multiplier is an important circuit used in electronic industry especially in Digital Signal Processing operations such as filtering, convolution and analysis of frequency. There are different types of algorithms used in multipliers to achieve the better performance. In this paper, 8*8 Wallace Tree and Dadda multipliers are implemented using two phase clocking subthreshold adiabatic logic. Its power dissipation is less when compared to their respective 8*8 CMOS multipliers. This paper can be implemented in HSPICE using 0.18μm CMOS standard process technology
A high performance interleaved bi-directional dc–dc converter with zero voltage switching can convert low-voltage reversible power sources to a high voltage dc bus individually or simultaneously by the phase-shift control, and also can step down the high-voltage dc bus to charge the power sources. The reversible power sources can charge each other. The circuit is designed as half-bridge circuit. The inductors in the proposed converter are designed to operate in synchronous conduction mode for achieving turn-on zero-voltage-switching (ZVS) of all switches. The effectiveness of the designed circuit topology, ZVS properties and the goal of high-performance conversion can be obtained.
This paper uses the Bridgeless Rectifier Circuit, coupled with the Interleaved Boost and “PFC” (Power Factor Correction) technology to design a high-efficiency AC/DC conversion circuit, to provide a load of 400V, 2KW. The system efficiency can reach up to 96%. The power factor is close to 1, the input current ripple is below 0.8A and the output voltage ripple is below 6V. In addition to the application in variable- frequency control air-conditioning, the proposed system can also be used for a wide range of variable frequency control motors and DC electric motors, such as household fans, DC electronic fluorescent lamps or variable- frequency control motors.
Low cost Instrumentation for ultrasonic velocity and attenuation measurements in liquids and solids is described in this paper. 1--10 MHz pulse generator is assembled using CMOS integrated circuits having pulse width of 2 to 60 microseconds. The wideband receiver is developed by using the Wideband Low Distortion, High Gain Operational Amplifier (OPA 643). The gain and bandwidth of the receiver are 50 dB and 10 MHz respectively. Transit time measurement has been performed by using the NI-LABVIEW and Multifunction I/O card NI-USB-6212. The system is found suitable, accurate and versatile for ultrasonic velocity and attenuation measurements.
