What is IGBT: Working, Switching Characteristics, SOA, Gate Resistor, Formulas
IGBT stands for Insulated-gate-Bipolar-Transistor, a power semiconductor which includes the features of a MOSFET’s high speed, voltage dependent gate switching, and the minimal ON resistance (low saturation voltage) properties of a BJT. Figure 1 exhibits IGBT equivalent circuit, where a bipolar transistor works with a MOS gate architect, while the similar IGBT circuit is actually […]
Electronic Candle Flame Simulator Circuit
This electronic candle accurately imitates the flickering flame of a lit wick, but it remains considerably cleaner, doesn’t drip, and poses no risk of setting your interior on fire. It only requires a handful of ordinary components and is powered directly from the mains with minimal energy consumption. Its lifespan will be exceptionally long. How […]
Sound Activated Remote Control Circuit
This sound activated remote control circuit can be used to operate any electrical load ON/OFF, through a double sound command. Thus, the circuit ensures that the load cannot be operated through any random single sound triggers, which makes the circuit very fool proof. Our device will require two shifted sound commands. However, the second sound […]
High Voltage DC Motor Speed Regulator Circuit
In the realm of motor control systems, high voltage DC motors play a crucial role in numerous industrial and automotive applications. Efficiently controlling the speed of these motors while ensuring operator safety and isolating sensitive components can be a challenging task. However, with the advent of advanced technologies, such as optocoupler motor controller power stages, […]
