BLDC Air Cooler Controller Connections and Working
Induction motor vs BLDC motor The air cooler industry is gradually shifting from traditional shaded-pole and capacitor-run induction motors toward Brushless DC (BLDC) motor technology. While the external appearance of the cooler may remain unchanged, the electrical system inside is significantly different. As a designer of BLDC cooler controllers, I have observed that most users…

Introduction to TVS diode
Definition of TVS Diodes Transient Voltage Suppression (TVS) diodes are essential components designed to protect sensitive electronics from voltage spikes and transients. These abrupt and extreme fluctuations in voltage can be induced by lightning, electrostatic discharge (ESD), or switching noise from other devices within the circuit. TVS diodes work by clamping overvoltage events to a…
