Exercise bicycle for accumulator charging
 Nekvapil, Jan ; Španěl, Petr (referee) ; Knobloch, Jan (advisor)
Semestral thesis is about possible solution construction of exercise bicycle with electric part working as a electric source. The first part of document introduces readers to issues about lead acid accumulators and charging, electronically commutated motors and electric converters. The second part shows potential solving constitution of exercise bicycle and we choose components and devices. EC motor could be connected with exercise bicycle by flat belt. Transfer energy is realized through active rectifier and simultaneously step-up converter to DC-circuit and accumulators. At the end of the document is compared existing similar products.
