These findings indicate compounds isolated from ethanolic extracts of Crotalaria sps., possesses pharmacological properties and potential to develop natural compounds based pharmaceutical products. The IC(50) values for ethanolic extracts of Crotalaria sps. was evaluated through the Linear regression analysis (R(2) ≤ 1).

STATCOM is used in a six-phase transmission system to improve voltage regulation and transient stability. Six-phase pulse width modulated voltage source converters are used in the design of STATCOM, and a decoupled current control approach is used to operate it. The voltage references used by the voltage source converters' pulse generator are produced using a decoupled control method. This control technique allows for the decoupling of the coupling effect or the dependence of the d and q currents on one another, which improves system performance under unusual and abnormal conditions. By using the pulse generator of voltage source converters, the inner current control loop and the outer voltage control loop are intended to produce the necessary reference voltages. Simulation results are presented using MATLAB/SIMULINK to check efficacy of proposed six phase STATCOM.
