This paper is based on the engineering requirements of intelligent fault diagnosis technology, and designes the information-enhanced fault diagnosis system for avionics power supply module. Firstly, we designed the framework of the system, gave the information that needed for fault diagnosis and the way to get it. Then, the fuzzy neural network model was established which combines the neural network...
Aiming at a storage system of high-speed data acquisition, it is designed with 6 channel,16-bit AD converter chip AD7656 and a programmable logic device EP2S90F102.The K9W8G08U1M chip made in SAMSUNG is selected as storage unit, and FPGA controls the needed logic for FLASH and AD converter. At the end of data acquisition, the stored data can be transmitted to the host through the USB2.0 interface...
Shift schedule and torque converter lockup schedule are designed based on parameters of the vehicle. In addition, Optimization of shift quality based on uniform design method, which can reduce test time, is put forward and the application method is specified.

As the number of transistors in microprocessors increases, their power demand increases accordingly. This poses design challenges for their power supply module called VRM (Voltage Regulator Module) especially when operated at sub voltage range. This paper presents the design of a new multiphase multi-interleaving topology that addresses these challenges. A lab scaled hardware prototype of the new...
Electronic unit pump (EUP) fuel injection system has prospective application in medium or heavy diesel engine. Developing an ECU of EUP diesel engine is necessary to meet emission regulations and economic requirements. The structure and working principle of EUP fuel injection system was studied. An ECU was developed, which consists of digital circuit, power supply module, driving circuit and sensor...
Pursuing rapid simulation speed and requiring reflections on more circuit details are always contradictory in computer simulations, especially for those of complex circuits such as a distributed power system. Simplified models of power supply modules are expected to establish a balance between above two requirements in implementing inter-connected system simulations. After reviewing a previously published...
As the number of transistors in microprocessors increases per Moore's Law their power requirement increases accordingly. This poses design challenges for their power supply module especially when microprocessors operate at sub voltage range. This paper presents a new multiphase topology that addresses these challenges. Laboratory tests on a hardware prototype of the topology shows improved performance...
To solve the problem of the original investment hedge when the fieldbus control system (FCS) substitute the distributed control system (DCS), we design a low-power intelligent pressure transmitter which is compatible with analog signals and digital signals. The pressure transmitter is designed based on HART protocol and composed with MCU module, sensor module, HART communication module, LCD modules...
This paper presents a power supply module (PSM) for SoCs (system on chip). This module, which is based on an improved LDO, has a wide input range and switchable power path. The proposed PSM can output a steady voltage of 6v as input voltage varies between 5.7 V-30 V, with a max error of 4.3%. It also provides a flexible power path. The SoCs will be supplied by either internal LDO or external power...
Wireless sensor networks may be used in the explosion environment, such as underground tunnel in coal mine. In order to assure sensor node work normally, the power of a sensor node must be intrinsic safe. The intrinsic safe power of a sensor node, which consists of power supply module and intrinsic safe protection module, is developed. The power supply mainly consists of current-mode controller chip...
In this paper, target identification and trajectory technology are analyzed. The tracking control algorithm based on the photoelectric sensors is proposed. The algorithm utilizes the errors of the location and the signal of route as input parameters, to regulate the output angle of the steering gear. The smart car system includes the straight trajectory control algorithm, the curvy trajectory control...
The impulsive acceleration of active protection elements such as armour plates or other terminal ballistics interception devices can preferably be realized by single-stage electromagnetic launcher systems using pancake coils. The technology with controlled multipartite coil assemblies represents a new supplementary topic in the entire field of ballistics. But the essential condition is the availability...
To treat sudden arrhythmias often happened in cardiosurgical operations, e.g., atrial fibrillation, ventricular fibrillation and ventricular tachycardia, it was necessary to develop special low-energy cardioverter-defibrillator with precise energy measurement and impedance compensation, working in both epicardial manner and endocardial manner. The system consisted of 4 main parts: cardioverter-defibrillator...

A multi-level approach to modeling power factor correction (PFC) rectifier and dc-dc converter modules in inter-connected switching power supply systems is illustrated in this paper. A three-level hierarchy for modeling these modules is proposed and defined. The most recent results from simulations and experiments are provided to show effectiveness of the proposed approach.
