One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric ...

Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

ROHM has developed the BD67871MWV-Z, a three-phase BLDC motor gate driver for medium voltage applications (12V to 48V systems). By including its proprietary gate drive technology TriC3, it greatly ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
