Abstract

A power loss estimation method for IGCT NPC-3L converter is discussed in this paper. The undetermined coefficients in switching loss calculation are obtained through double-pulse test. Traditional loss calculation method based on formula is restricted by one particular modulation strategy and the estimation is inaccuracy due to idealized working conditions. To solve this problem, a universal NPC-3L power loss simulation estimator suitable for any modulation strategies is presented. Output current ripple and DC link voltage fluctuation are also considered in the estimator. Through power electronic building block (PEBB) half bridge power test, the accuracy of the estimator is verified to meet the engineering requirements.
