Power MOSFETs require a gate drive circuit to translate the on/off signals from an analog or digital controller into the power signals necessary to control the MOSFET. This paper provides details of MOSFET switching action in applications with clamped inductive load, when used as a secondary synchronous rectifier, and driving pulse/gate drive transformers. Potential driver solutions including d...

A low-power and small-area scan driver using depletion-mode amorphous-InGaZnO (a-IGZO) thin-film transistors (TFTs) is proposed for 10-inch quadruple extended graphics array (QXGA, 2048 × 1536) panels. The proposed scan driver is realised in a small area using 11 TFTs and improves power consumption by removing short circuit current. Measured results show that the power consumption of the propos...

This paper presents two high-voltage circuits used in power management, a switching driver for buck converter with optimized on-resistance and a low dropout (LDO) voltage regulator with 2-stacked pMOS pass devices. The circuit design is based on stacked MOSFETs, thus the circuits are technology independent. High-voltage drivers with stacked devices suffer from slow switching characteristics. In...

The electroacoustic efficiency of high-power actuators used in thermoacoustic coolers may be estimated using a linear model involving a combination of six parameters. A method to identify these equivalent driver parameters from measured total electrical impedance and velocity-voltage transfer function data was developed. A commercially available, moving-magnet driver coupled to a functional the...

Potential shortage of world wide petroleum supply in the near future has created an enormous demand for green vehicles that use higher power electric motor drive in their traction systems. Application of power electronic modules in automobiles has generated the need for reliable and low-cost high-temperature electronics which can operate at the extreme temperatures that exist under the hood. In...

On the basis of various and recent research studies, it is apparent that highway designers must become more concerned with the relation­ ship between highway design and traffic behavior. An excellent example of current interest in highway design is the design of acceleration and deceleration lanes. In order to obtain maximum efficiency and safety in the operation of acceleration and deceleratio...
