Low switching frequency in medium voltage and high power application of power converters is desired in order to minimise the switching losses. Pre-programmed pulse width modulation technique is extensively used in such applications as it ensures better quality output waveform. But in its implementation, the main challenge is the calculation of switching angle values from the system of highly nonlinear transcendental equations which are obtained by Fourier series analysis of the output waveform. In this paper, a differential evolution-based evolutionary intelligent technique is proposed to calculate the optimised switching instants in a wide band range. The sensitivity of the switching instants as a function of modulation index is minimised as wide band solution permits flexibility in its operation. Computational, simulation and hardware results using DSP controller TMS320F2812 are presented to corroborate the concept.

The power quality problems of the utility voltage are transferred to the grid-tied microgrid. With the conventional organisation of a hybrid AC-DC microgrid, the controller cannot compensate the voltage of the AC bus. The paper offers the bi-directional series converter between the common DC bus and the utility to compensate the sag/swell/harmonics of the utility voltage. The controllers are designed based on the instantaneous reactive power theory and predictive control. The interfacing converter compensates the reactive power and harmonics components of the nonlinear AC load and the voltage of the DC bus along with bi-directional transmission power. The performance verification is done by simulating the typical microgrid in MATLAB/Simulink. The AC bus voltage and utility current become pure sinusoid. The results show improvement in the THD of source current and load voltage while the voltage of the DC bus is controlled at the reference voltage.

Dynamic voltage restorer (DVR) has proven to be the most coherent, effective and economic answer to voltage-based power quality problems. This work details the design, investigation and experimental validation of reweighted zero-attracting least mean square (RZA-LMS) based DVR addressing the issues like voltage sag, voltage swell, voltage harmonics, voltage imbalance and combination of these. The RZA-LMS based control algorithm is proposed for producing reference voltage signals. The features of proposed algorithm include finite-time convergence, simplicity and improvement in the robustness of the system against varying parameters. The viability of DVR controller is assessed by employing MATLAB/Simulink and Simpowersystem software. The performance of proposed DVR is experimentally investigated using digital real-time simulator.
