SEPIC Voltage Control

Since R2024a

This example shows how to control the output voltage of a single-ended primary-inductor converter (SEPIC). The SEPIC is a form of DC-DC converter designed to deliver a regulated positive output voltage, regardless of whether the input voltage is higher, equal to, or lower than the intended output voltage. The Control subsystem adjusts the duty cycle of the semiconductor switch to regulate the output of the SEPIC. To adjust the duty cycle, the Control subsystem uses a PI-based control algorithm. The input voltage is constant throughout the simulation. A resistor provides the load for the system. The total simulation time is 0.1 seconds.
