IPC: H02M7/797
Filed: 2001-06-11
Abstract: PROBLEM TO BE SOLVED: To enhance regeneration energy efficiency by realizing necessary braking force property so as to actuate a regenerative brake or an electric brake, in a full-speed range of high speed region to zero speed. SOLUTION: When regenerative braking force runs short in a high seed range, this controller opens a current breaker 10, and connects an inverter device 3 with a DC power source 9 in series through a rectifier 8. Here, they are connected so that the direction of a power voltage Va and the direction of an output end voltage Vb are the same. At this time, the potential of the negative DC input terminal an inverter device becomes-Vb, and an inverter input voltage Vc becomes the sum (Vc=Va+Vb) of the power voltage Va and the output end voltage Vb of the DC power source 9. Hereby, this can increase the inverter input voltage Vc, so that the augmentation of braking force in the high speed range becomes possible.  At this time, since a regenerative current Ib flows by driving it regeneratively, the power Va×Ib is regenerated in a DC power source 1, and the DC power source 9 is charged with the power Vb×Ib.
