文摘

AC small signal model is proposed and used to analyze a Trans-qZSI working in CCM. System is tolerant enough toward small variations in L and C. Losses associated to the L will degrade the achievable value of the steady state. Decreasing D deteriorates the control stability of the system. Higher load resistance, lower output current, lowers the damping factor.
