摘要： A current mode power conversion system and method are described that provide a stable output voltage and a maximum-limited output current to a load. The system comprises: a feedback control linearly operable so as to control the output voltage across the load during constant load conditions, and non-linearly operable so as to control the output voltage across the load during certain detected changes in load conditions above a predetermined threshold so as to speed up the transient response of the power conversion system.

摘要： A testing apparatus and method for testing a semiconductor device, and more particularly a test arrangement for measuring a guaranteed power loss of a semiconductor module, not requiring the module to have on-board decoupling capacitors for the power loss test. The conventional pogo-pin array and test socket are replaced by a novel low cost anisotropic conductive elastomer and a low cost socket, the conductive polymer providing electrical communication between the socket and the module under test.

摘要： A modular drilling system including a plurality of different size drill bits which can be interchangeably mounted on a common tapered male connecting portion of a drill rod assembly. The tapered male connecting portion may be formed directly onto a tapered drill rod of the assembly or may be formed on an adapter which is threaded onto a threaded drill rod of the assembly. Each bit includes a female connecting portion having a generally cylindrical tapered surface mating with a corresponding tapered surface of the male connecting portion and at least three planar sections adapted to provide positive engagement with corresponding planar sections of the male connecting portion.

摘要： Parallel transistor circuits with reduced effects from common source induction. The parallel transistors include physical gate connections that are located electrically close to one another. The parallel circuits are arranged such that the voltage at the common gate connection resulting from transient currents across common source inductance is substantially balanced. The circuits include switching circuits, converters, and RF amplifiers.
