DESIGN OF ANALOGUE PULSE GENERATOR FOR NOVEL CONCEPT OF MULTI-LEG BOOST CONVERTER

This article deals with design control for novel concept of multi-leg boost converter. This new concept allows effective utilization of energy from input source. The effective utilization of input energy is ensured by adding five parallel legs to the conventional single-leg boost converter. Appropriate algorithm of switches control allows converter to take the input source energy one of these six parallel legs in every moment. This algorithm allows multi-leg boost converter to work with high efficiency of energy conversion in compare with single-leg boost converter. The multi-leg boost converter continually delivers the energy of input source to the load. In this case, the time interval when the output energy is equal to zero is removed. The simulation and experimental models were built and measured to verify the theoretical properties of design control and correct function of multi-leg boost converter.
