The two most common forms of control in dc/dc switching power converters are CM (current-mode) and VM (voltage-mode) control. Each method has its own advantages and disadvantages. CM control provides ...

A buck converter is the most widely used power supply topology, and recent trends indicate that next generation switching controllers must be able to provide stable and efficient operation at very ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...

Editor's Note‘Agile Electronics Stories’ is a corner that keenly examines the small details of electronic and mechanical products and devices. From hot new products frequently appearing in ...

Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

Mathieu Renaud, Senior Power Management Designer, Intégration Dolphin Inc. Yves Gagnon, Executive Director, Intégration Dolphin Inc. Inductor-based Switching Regulators (SR) have historically ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...
