Embodiment Construction

[0032] The USV according to the present invention is in figure 1is shown unipolarly, ie only the power line of the USV is shown and the neutral line of the USV is not shown. Likewise, the DC voltage is shown bipolar.

[0033] The USV according to the invention has a rectifier 1 , an energy store 2 , an inverter 3 and a switching device 4 . The input of the rectifier 1 is connected to the power supply network AC1. The output of the rectifier 1 is connected on the one hand to the energy store 2 and on the other hand to the input of the inverter 3 . The output terminal of the inverter 3 is connected to the network AC3 to be protected.

[0034] Depending on the switch position, the switching device 4 can connect the supply network AC2 with the network AC3 to be protected. If the rectifier 1 and the inverter 3 are functioning without fault and the supply network AC1 is also fault-free, the power supply to the network AC3 to be protected is supplied via the rectifier 1 and the i...

Abstract

An uninterruptible power supply with a rectifier, energy store for storing electrical energy, inverter, switching means and a controller is provided. The rectifier is connected to a rectifier input to a supply grid, wherein the energy store is connected to a rectifier output and to an inverter input of the inverter. A network or load to be protected is connected to an inverter output of the inverter. The rectifier input or a supply grid is connected via the switching means to the inverter output. The rectifier, the inverter and the switching means are controlled by the controller. The arrangement includes means for supplying auxiliary current. Each means for supplying auxiliary current is connected with an input for the supplying auxiliary current to the first control part and an input for supplying auxiliary current to the second control part, for supplying the control parts with electric energy.

Description

technical field [0001] The invention relates to a device for uninterrupted power supply, comprising: a rectifier, an accumulator for storing electric energy, an inverter, a switching device and a control device. The rectifier can be connected to a power supply network by means of a rectifier input. The energy storage is connected to the rectifier output of the rectifier and the inverter input of the inverter. The network to be protected or the consumer to be protected can be connected to the inverter output terminal of the inverter. The rectifier input or the supply network can be connected to the inverter output via the switching device, and the rectifier, the inverter and the switching device can be controlled and / or regulated by means of the control device. Background technique [0002] The prior art discloses many such devices for uninterruptible power supply, referred to as USV for short. In addition, here, it is divided into offline USV (Offline-USV) and online USV ...
