Analysis of a Boost Converter Circuit Using Linear Hybrid Automata

Boost converter circuits are an important component in electrical and electronic systems. Serving as energy converters, they increase the voltage of a source. In mobile devices, high voltages can be achieved in this way, with a relatively small number of accumulator cells. Without this or a similar technique, it would be difficult to supply electric cars with the necessary voltages of about 500V . During the design and optimization of such analog systems, formal methods are rarely applied, in contrast to the computer aided design and verification of digital systems. The choice of the system parameters – capacitors, inductors and resistors – is mainly based on the expertise of the designers. This process is supported by simulation tools. Results on the modeling and formal verification of analog oscillator circuits have been reported [DDM04,FKR06]. A promising approach is the modeling of analog circuits using hybrid automata.
