static regulation

"Static regulation" generally refers to regulations or rules that do not change or are fixed in nature. They are often contrasted with dynamic regulations that can change in response to changing circumstances or conditions. Static regulations may include laws, policies, or procedures that are established to provide consistency and stability in a particular system or environment. For example, a company's code of conduct or a government's constitution are examples of static regulations that are designed to guide behavior and decision-making in a consistent manner.

DCDC static regulation

DC-DC static regulation is a technique used to regulate the output voltage of a DC-DC converter without using any feedback control loop. In this technique, a fixed voltage is applied to the input of the converter, and the output voltage is regulated by adjusting the duty cycle of the converter's switch. This is achieved by using a voltage divider network and a comparator to compare the output voltage with a reference voltage. The comparator then adjusts the duty cycle of the converter's switch to maintain a constant output voltage. DC-DC static regulation is simple and efficient, and it is commonly used in low-power applications where the load is relatively constant.
