Title:
電圧切換え装置
Document Type and Number:
Japanese Patent JP4267826
Kind Code:
B2
Abstract:
A voltage switch-over device comprises a first power rectifier, a second power rectifier, and a charger, the first power rectifier being connected to the charger. Mains leads connect the charger to a power supply, and a mains evaluation unit is coupled to the charger, the mains evaluation unit switchably connecting the second power rectifier to the power supply and to two consumers consisting of balanced primary modules activating at least one transformer. There is a first connection including a capacitor between the positive potential of the first power rectifier and the negative potential of the second power rectifier, and a second connection includes a capacitor between the negative potential of the first power rectifier and the positive potential of the second power rectifier, a respective one of the capacitors being arranged in an independent current circuit supplying a respective one of the consumers. A control device is connected to the consumers.
