We take a look at a new solution that is said to overcome the traditional challenges of controlling in all four quadrants with an AC motor.

A startup seeks a digitally synthesizable timing alternative to convectional crystal and PLL solutions based on analog ...

ac phase control circuits, along with window-type software and microprocessor control software. The system is designed to control home appliances' on/off, to regulate their output power, and to set ...

This paper presents a fully-digital, phase locked LDO implemented in 32 nm CMOS. The control model of the proposed design has been provided and limits of stability have been shown. Measurement results ...

DIACs, due to their bidirectional and symmetrical switching, are widely used as triggering devices in phase control circuits for lamp dimmers, heat control, motor speed control, etc. Although a TRIAC ...
