LABORATORY BENCH FOR ELECTRIC DRIVE ANALYSIS OF DIRECT CURRENT WITH REVERSIVE PULSE WIDTH CONVERTER

摘要

The laboratory bench for electric drive analysis of direct current with reversive pulse width converter includes a power transistor bridge, an input rectifier, direct current circuit capacitance, control system. To regulate rotor voltage the power bridge transistors operate in the pulse-duration modulation mode. The pulse-duration modulation power supply is performed with a safe voltage level through an input transformer. In order to provide for demonstrativeness of a control system point and power part through connectors are brought to separate schematic circuit diagram-board. The points are located on the schematic circuit diagram as pins. The bench is arranged in small variant in the plastic case to allow visually study applied circuity engineering decisions of the pulse width converter structure.
