Description
A self-excitation type semi-regulated switching regulator is a type of power supply circuit that combines elements of both switching regulators and linear regulators. It is designed to provide a regulated DC output voltage while also offering some advantages of switching regulators, such as high efficiency and compact size.
Features:
1. Regulation: The circuit includes a linear regulator section that provides basic voltage regulation. It utilizes a feedback mechanism to compare the output voltage with a reference voltage and adjusts the control element accordingly to maintain a relatively constant output voltage.
2. Self-Excitation: The term “self-excitation” refers to the ability of the circuit to start up and generate the regulated output voltage without requiring an external power supply for the control circuitry. This feature allows for a simpler overall system design.
3. Switching Element: Similar to a switching regulator, a self-excitation type semi-regulated switching regulator employs a switching element (typically a transistor or a MOSFET) to switch the input voltage on and off rapidly. This switching action helps achieve high efficiency by reducing power dissipation compared to linear regulators.
