Abstract :
The efficiency of two systematic state space based simulation techniques is assessed by direct comparison. One is based on the evaluation of the algebraic solution to the state space differential equations. The other is an enhanced variable step length trapezoidal algorithm. Both techniques have been applied to an undamped current source inverter and a 6-pulse rectifier with a smoothing capacitor with good results. The conducted simulations show the state space solution evaluation algorithm to be more efficient for harmonic computation
