Streszczenie

Boost DC/DC pulse converter structure with regard to conduction power losses for Continuous Current Mode has been analyzed in the paper. Simplified model of converter which takes into account the nonlinearity of the static characteristic switches was usedfor theoretical analysis. The models of the transistor and diode whose static characteristic are modeled as in series connection ideal electronic switch, the constant voltage source and dynamic effective resistance have been used. The dynamic losses of powers occurring in the switching process of electronic switches were not captured in the work. The proposed model of the converter has the use in the case, when it works at low switching frequencies, when the losses of switching are considerably smaller than the losses of conductivity. This land of model is useful, particularly in the case of the converter supplied the low voltage, when the voltages loss on electronic switches is significant. Analysis was performed for Continuous Current Mode (CCM) with voltage step up. Results of theoretical analysis have been presented and were verified by simulation. TCAD circuit simulator was used for simulation. Simulations confirm results of theoretical analysis.
