Charismatic, ideological, and pragmatic leadership: Multi-level influences on emergence and performance

The relationships among organisational culture, business environment, business strategy and functional strategies are rarely investigated in a holistic perspective. This leads to reductionism in modelling and prevents the full exploration of the potentially complex relationships among cultural orientation, business strategy and functional strategies and their impact on organisational performance. This paper, based on a sample drawn from food manufacturing businesses in Zimbabwe, recognises the pervasive impact of organisational culture on organisational strategy and functional strategies. As a result, it acknowledges the multi‐level impact of cultural orientation – allowing for the building of a conceptual model, linking cultural orientation, business environment, organisational strategy, functional strategies and performance – which is subsequently empirically tested.

Vhdl Code

This paper presents the design of the Multi-Level Inverter circuit based on the switched ladder topology using the angle events for the level changes. The change of events for the inverter is formulated using the Half Height Algorithm. The VHDL code is utilized for the generation of the angles as digital equivalence with the resolution of 27 bits. In ladder topology, there are several types of inverter namely Binary Ladder Inverter, Ye Progression, Luo Progression. Among all these topologies, the Trinary Ladder topology is advantageous for the number of levels attainment with the less number of switches. Also, the carrier-based modulation is erroneous with the High THD% and low Voltage Parameter values. The use of the non-carrier half-height method manipulates the accurate angle to measure acceptable THD %. The proposed Trinary Switched Ladder Inverter is cross-compiled with Xilinx Vivado and Matlab Simulink Took to evaluate the parameters such as THD%, VRMS, VPEAK, for the 27-level. The parametric analysis exhibits improvement in the proposed Ladder topology with cost, size, and performance when synthesized using the Xilinx Vivado tool.

Cascaded Multilevel Inverter

This paper proposes a Hybridized Symmetric Cascaded Multilevel Inverter for voltage levels ranging from 5 levels to 17 levels. The proposed Multi Level Inverter (MLI) topology is built using a modified H-bridge inverter that results in an increased output voltage levels with a smaller number of solid-state switches. This technique enhances the h-bridge configuration from three level to five level by means of a bi-directional switch at source. Gating pulses of hybridized symmetric MLI are generated through staircase modulation. The operation and performance of the proposed topology is tested for different output voltage levels, simulation results prove that the proposed technique results in less THD at all levels with lesser power consumption and are easily applicable for renewable energy applications.
