Transformerless Power Supply

Let's explore how to build a transformerless power supply circuit that converts 220V AC to DC. This type of circuit is incredibly useful for many electronics projects. But before we dive into the details, a crucial word of warning: working with 220V AC is dangerous. Safety must be your absolute top priority to prevent accidents.
This circuit design offers a flexible and adaptable way to power your projects. It’s a great option for many applications. However, if you're not completely comfortable with the technical aspects, or if you're new to electronics, it's always safer to stick with a traditional transformer-based power supply. If you have any doubts, that's the recommended route.
