Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Vishay Precision Group, Inc. announced that its Vishay Foil Resistors product line (VFR) has introduced the new high-precision Bulk Metal® Foil Burden through-hole resistor. Designed for connection to ...

The power supply is the backbone of any electronic device, and its performance is especially critical in the growing mobile consumer market, where not only accuracy but also power efficiency is ...

Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...
