    • PURPOSE:To maintain power consumption output as a constant value by varying the power conversion efficiency of a converter for converting the power of the induction coil output in response to the detecting level of an induction winding output detector. CONSTITUTION:An induction winding output detector 16 detects the output of an induction winding 5 to supply a detecting level in response to the speed of a railcar to a power converter 12. The converter 12 varies the power conversion output via the detecting output of a current detector 11 for detecting the output current of a rectifier 10, and varies the power conversion efficiency in response to the output level of the detector 16. Thus, since the power conversion output of the maximum output in response to the speed of the railcar is supplied to a battery, the power of the maximum output is always outputted from the inverter 8 irrespective of the variations in the speed of the railcar and the capacity of a load.
