Introduction, Q&As-lim10-2 - Application Note __ MiniCircuits.com
Limit Inrush Current In High-Power Applications - 02/03/11 EDN-Design Ideas Protect circuits from high current until a capacitor charges. A high-power offline supply is nothing more than a half- or full-bridge dc/dc converter. Rectifying the ac line yields a dc voltage that feeds the converter. At power-supply turn-on, the bulk capacitor of the uncontrolled rectifier is completely discharged. It results in a huge charging current for a high instantaneous line voltage because the discharged bulk capacitor temporarily short-circuits the diodes of the rectifier stage.

Limit Inrush Current In Low- to Medium-Power Applications - 11/04/10 EDN-Design Ideas A MOSFET and IGBT guide current to safe places. Design by JB Castro-Miguens, Cesinel, Madrid, Spain and C Castro-Miguens, University of Vigo, Vigo, Spain Limit switches control dc-motor H bridge - 03/05/09 EDN-Design Ideas Mechanical and electronic switches provide interlocks, preventing motors from overrunning their bounds Design by Andreas Grün, Wedemark, Germany
Limiting Amplifier is Digitally Programmable - 06/04/98 EDN-Design Ideas To generate high voltages with proper insulation between "hot node" and rest of circuitry, a car ignition coil can function in place of a high-voltage transformer. se coils have voltage ratings of approximately 20 kV,.

Limiting Amplifier Makes Efficient A/D-Converter Drive - 09/02/96 EDN-Design Ideas Limiting amplifiers are useful for protecting circuitry that has a limited input range. A classic example is an input buffer for an A/D converter. Many A/D converters are susceptible to damage if the input significantly exceeds the specified range.
