What does a solid state regulator do to maintain a level output voltage?

A solid-state regulator maintains a stable output voltage primarily by varying conduction. When the load demands an amount of current that would affect the output voltage, the regulator can adjust its conduction in response to these changes. This is done by controlling how much of the input voltage is allowed to pass through the regulator, effectively modifying the duty cycle in which current is allowed to flow, ensuring a consistent output under varying load conditions.

This method relies on semiconductor devices such as transistors that can quickly and efficiently turn on and off, adjusting the amount of current flowing based on the feedback received regarding the output voltage. Thus, as the load increases or decreases, the regulator senses the change and adapts the conduction level accordingly, maintaining a steady output voltage.

While varying frequency, switching on and off, and changing resistance are all concepts that may pertain to different types of electrical regulation or control, they do not accurately describe the specific function of solid-state voltage regulation. Solid-state regulators primarily focus on adjusting conduction, which is essential for providing consistent voltage output.
