With the increasing popularity of alternate power sources, such as solar and wind, the need for static inverters to convert dc energy stored in batteries to conventional ac form has increased ...

Pulse Width Modulation or PWM technology is used in Inverters to give a steady output voltage of 230 or 110 V AC irrespective of the load. The Inverters based on the PWM technology are more superior ...

Pulse-width modulation is a simple way to modulate, or change, a square wave. In its basic form, the duty cycle of the square wave changes according to some input. The duty cycle is the ratio of high ...

I am a versatile writer with a keen interest in exploring and sharing insights on lifestyle, food, and technology. With a deep curiosity about the world around me, I enjoy delving into various ...

Toshiba is offering its first single-chip sensorless motor controller as an application specific standard part which offers full-wave sine wave PWM motor drive output. Intended for brushless DC (BLDC) ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...
