Analysis of the averaging for the dc/ac half-bridge converter and the three-level half-bridge neutral point clamped

Modeling and simulation of power-electronic systems is essential for design and verification of numerous electrical energy systems. Uses of detailed switching models increase the computing time. This paper presents the averaging of the DC/AC half-bridge converter and the three-level half-bridge neutral point clamped (NPC), as well as their computational assembling. The equivalent models are validated through their comparison respect to the full models simulated in the PSCAD software. Results demonstrate that good approximations have been attained.
