Sliding mode (SM) and Proportional-integral-derivative (PID) controller are implemented for Buck converter in a continuous conduction mode. A closed-loop controller system is implemented and goes through the transient time response of buck converter. Sliding mode controller is worked as robust controller and can be used to reduce the Delay time and settling time of the system. In power drives c...

Solid-state switch-mode rectification converters have reached a matured level for improving power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input ac mains and precisely regulated dc output in buck, boost, buck–boost and multilevel modes with unidirectional and bidirectional power flow. In this paper, an improved power quality converter employing con...

Randomized Pulse Width Modulation (RPWM) deals better than Deterministic PWM (DPWM) with Electro-Magnetic Compatibility (EMC) standards for conducted Electro-Magnetic Interferences (EMI). In this paper, we propose a dual RPWM scheme for DC-DC voltage converters: the buck converter and the full bridge converter. This scheme is based on the comparison of deterministic reference signals (one signa...

this paper presents a novel control method to improve the efficiency of low-voltage dc-dc converters at light loads. pulse width modulation (pwm) converters have poor efficiencies at light loads, while pulse frequency modulation (pfm) control is more efficient for the same cases. switching losses constitute a major portion of the total power loss at light loads. to decrease the switching losses...

A single-inductor dualoutput (SIDO) buck converter has recently found applications in handheld battery-powered electronic devices. The circuit operation and the functional interdependencies among basic converter parameters such as dc voltage gains, transistor duty cycles, and load current levels are much more complicated than those of the singleoutput counterpart. In this project, a rigorous an...

Cross regulation is the main technical drawback of a Single-Inductor Multiple-Output (SIMO) dc-dc converter. This paper proposes a multivariable digital controller to suppress the cross regulation of a SingleInductor Dual-Output (SIDO) buck converter in Continuous Conduction Mode (CCM) operation. The controller design methodology originates from the open-loop shaping of the Multi-Input Multi-Ou...

Photovoltaic power generation system implements an effective utilization of solar energy, but generally has very low conversion efficiency. Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A MPPT system has been developed...
