Application Note 694 A DMOS 3A, 55V, H-Bridge: The LMD18200
ثبت نشده
چکیده
The switching power device shown in Figure 1 is called an H-Bridge. It takes a DC supply voltage and provides 4-quadrant control to a load connected between two pairs of power switching transistors. Because the switches allow current to flow bidirectionally, the voltage across the load and the direction of current through the load can be of either polarity. H-Bridges are often used to control the speed, position or torque of DC and stepper motors. Traditionally implemented with either discrete or monolithic bipolar transistors, fully integrated solutions are becoming increasingly popular in printer, plotter, robotics and process control applications that require 0.5A to 3.0A and operate from 12V to 55V. The LMD18200 was designed to operate within this range and was optimized for such applications.

متن کاملMathematical Programming Approach To Allocate Local Or National Resources For Bridge Maintenance Rehabilitation & Replacement Planning (RESEARCH NOTE)
Today’s, the transportation facilities such as terminals, street, bridge, etc, represent the major investment in highway network. Every year tremendous resources should be invested to maintain these facilities. Among them, the Bridge Management System (B.M.S.) has been necessitated by large imbalance between extensive bridge repair and maintenance needs and limited available budget. So the main...
متن کاملApplication of SVC on Large Synchronous Motors Based on LOC Design (RESEARCH NOTE)
This paper describes the application of static var compensators, (SVC) on an electrical distribution network containing two large synchronous motors, one of which is excited via a three-phase thyristor bridge rectifier. The second machine is excited via a diode bridge rectifier. Based on linear optimization control (LOC), the measurable feedback signals are applied to the control system loops o...
متن کاملConstriction Scour In Pressurized Flow Condition (RESEARCH NOTE)
When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
