Toshiba Electronics Europe has introduced two new sine‑wave pulse‑width‑modulated (PWM) drive controllers designed for three‑phase brushless DC (BLDC) motors, expanding its motor control portfolio.

The principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For as long as this type of control considers the ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...
