Voltage Drops on Battery Lines, of 3ms – 6 sec, Can Cause Interrupts

Posted on 01 March 2019

      Converters 10W - 500W DC/DC avoid system interruptions Supply line interruptions and voltage drops on battery wiring may lead to unexpected system behaviour in electronic systems. By Willi Spiesz, Grau Elektronik, Karlsbad, Germany   In safety related electronic systems, like brake and door control systems used in trains or busses, system interruptions [...]

Interleaving Enhances Power Factor Corrector Performance

Posted on 01 September 2019

       Interleaving reduces dramatically the ripple current amplitude To limit the input current harmonics drawn by the off-line equipment, several international regulations, such as the EN62019-3-2 are in place. In order to limit the harmonic currents, power factor correction (PFC) circuits are used. By Marcus Zimnik, Texas Instruments   The need for power [...]
