Whether it's an electronic noob or an expert engineer, all require this indispensable piece of equipment called the power supply unit. This is because no electronics can run without power, to be precise a low voltage DC power, and a power supply unit is a device which is specifically meant for fulfilling this purpose.

We can convert the High voltage AC into Low voltage DC without using the Transformer. This is known as Transformerless power supply. The main component of a Transformerless power supply is Voltage dropping capacitor or X-rated capacitor, which are specially designed for AC mains. This X rated capacitor is connected in series of Phase line of AC, to drop the voltage.

Learn about different types of transformers, including step-up, step-down, isolation, and autotransformers. Explore their working principles and practical applications in power systems, electronics, and industrial use.

The MT3608 power module is a step-up(Boost) converter module intended for small and low-power applications.

Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem almost every controller comes with a sleep mode, which help developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power saving mode by turning off the unused module.
