Use of explicit integration methods for power electronic circuits with ideal switch models significantly improves simulation speed. The PLECS package [1] has effectively used this idea; however, the implementation details involved in PLECS are not available in the public domain. Recently, a basic framework, called the ``ELEX" scheme, for implementing explicit methods has been described [2]. A few modifications of the ELEX scheme for efficient handling of inductors and switches have been presented in [3]. In this paper, the approach presented in [3] is further augmented with robust schemes that enable systematic equation formulation for circuits involving switches, inductors, and transformers. Several examples are presented to illustrate the proposed schemes.
