If you are using an electronic component, it most likely has a voltage regulator. A voltage regulator is an instrument that helps maintain a constant voltage, such as for a refrigerator, LED TV, or computer, effectively stabilizing the DC voltages used by components. Voltage regulators can either have a simple feed-forward design or a negative feedback design. Voltage regulator design depends on AC or DC voltage requirements; thus, it can be an electromechanical mechanism or electronic components. There are different voltage regulators available based on different mechanisms and factors, such as the application, voltage requirements, power conversion, etc. In this blog, we will briefly discuss active regulators, DC voltage stabilizers, electronic voltage regulators, and electromechanical regulators.
