A dual power supply circuit is designed to provide symmetrical voltage outputs, such as +12V and -12V, from a single source. This is achieved using components like voltage regulators, transformers, and bridge rectifiers. The precise construction of a dual power supply circuit plays a crucial role in reducing ripple and ensuring smooth power flow to sensitive components.
