Abstract

PURPOSE:To sustain operation through remaining normal CVCF inverters by disconnecting failed CVCF inverters from a system by means of a switch, short- circuiting an input side filter capacitor, and then releasing a load by means of an output side switch. CONSTITUTION:DC voltage taken in through a pantograph 1 and a DC reactor 2 is divided through a plurality of filter capacitors(FC) 3-5 connected, respectively, with CVCF inverters 9-11. The inverters 9-11 are operated synchronously and the outputs therefrom are shaped through AC filters 12-14 and combined through a three-phase transformer 18 to produce an AC output for operating various auxiliary machines in a vehicle. Upon failure of the CVCF 9, for example, it is disconnected by means of a switch 6 and a CF 3 is short-circuited to open switches 15, 19. Remaining CVCFs 10, 11 then perform DC/AC conversion and power is fed from the transformer 18 to low power loads, e.g. a controller and a fluorescent light 21 thus sustaining the operation.

However, in any of these types of vehicle auxiliary power supply units, maintenance is easy, but since semiconductor elements are controlled by complicated electronic circuits, noise is generated during business operation. It may stop suddenly. In that case, since the control device required to drive the vehicle depends on the output of the CVCF inverter for its control power source, it becomes difficult to drive the vehicle, and the interior lights also go out, which leads to a safety problem. There was a possibility that the above problem would occur.

Further, in the case of the capacitor voltage dividing type multi-stage connection inverter system, even if only one system out of a plurality of CVCF inverters operating in synchronization fails, another healthy CVC will operate.
There was a problem that the F inverter could not be operated and wasted. Therefore, in order to prevent such a problem, another auxiliary power supply that is in operation employs a method of performing extended power supply.However, since the capacity of each device is designed in consideration of the extended power supply, the capacity is normally reduced. There was a problem that it was excessive and wasted on equipment.
