Dynamic behavior analysis using pspice for linear and non-lineal closed loop controllers for non resonant ballast

The Pspice program is an electronic simulation package widely used in electronic ballast simulation, because Pspice is based on visual programming, then ballast modifications are easily made with this software. However, for control loop simulations Pspice is very slow, and convergence problems appear constantly, due to the high complexity in semiconductor and analog electronic component models plus the high switching frequency effects. In this paper a fast Pspice simulation scheme for an electronic ballast with closed loop controls (PI control and Sliding Mode Control: SMC), without semiconductors and analog electronic components, is proposed. Simulations, with a dynamic non linear lamp model, and experimental resuits of the electronic ballast are presented.
