چکیده
This paper present a pulse width modulation non-isolated buck converter using PID controller. The buck converter constituted by one Gto, one inductor, one capacitor, one diode and one load resistor. In this the buck converter connected to the PID controller, PID controller calculate an error value as the difference between a measured process variable and a desired set point. The proportional P depends on the present error, integral I accumulate the past error and derivative D predict the future error. The performance of buck converter has been studied and is undertaken for their theoretical verification, graphical performance and matlab simulation.

متن کاملSliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency
In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...
