Abstract: Nowadays it has become necessary to increase the use of renewable energy sources. However, the main disadvantages of RES are the uncontrollability and limited availability, depend on weather conditions. The application of DSP processors for energy management system of renewable and non-renewable energy sources intended for grid connected applications is presented here. The presented scheme explains the generation of PWM gated pulse signals using the Texas Instrument’s DSP with the help of MATLAB Code/Simulink and Code Composer Studio. The main components for the switching and regulation of the power sources are DC-DC and AC-DC converters. The mathematical model and state space equations for a small signal model of boost converter operating in continuous conduction mode and 3 phase rectifier for unity power factor are developed. Based on the transfer function controllers are designed and implemented it on TMS320F28335 DSP processor with the help of MATLAB Simulink and CCS. The proposed design ensures good tracking performances and maintains stability in the system. Since the control methods allow real time modification in the required reference according to the change in required output. Designed controller capabilities, load voltage variations and inductor current variations are demonstrated through MATLAB simulation results.

TL;DR: In this article, the SAZZ Converter with Soft Switching technique is applied to the Fuel Cell System to improve the output voltage to desired value. And three different filtering techniques of SAZZ converter are analyzed.
Abstract: In this paper, the SAZZ Converter with Soft Switching technique is applied to the Fuel Cell System to improve the output voltage to desired value. The Output voltage of this converter is obtained as a DC Voltage, which is connected to an impedance network, to remove the ripples present in the circuit. A 3 phase inverter operating at 180 degree mode is connected with the system. Filtering technique is applied to reduce the Harmonics obtained in the system. Open loop PWM switching is adopted. An Impedance network is connected to reduce the ripples present in the circuit. In order to boost the obtained value this network is connected in form of Z-source with a three phase inverter. This inverter operates at 180 degree mode. Open loop PWM triggering is adopted to obtain AC output and the obtained AC Voltage contains harmonics of both odd and even harmonics of lower and higher order. Higher order harmonics are eliminated with the help of Filters while lower order harmonics are eliminated by a Current Injection technique. Here three different filtering techniques of SAZZ converter are analyzed. Three techniques of Filter are compared and evaluated. This filtering technique is developed to reduce the third harmonic content in load side. Therefore they are suitable to implement a system capable of converting DC to AC with FUEL Cell as DC Source. Other parameter considered is peak to peak (rms) voltage. The study determines that LC filtering technique is most useful mainly due to low harmonic content (third order). FFT analysis is done to obtain values of these three filtering techniques.
