2.1 Functional Description
The product is developed for charging and discharging batteries and equipped with
modern efficiency optimized technology. It works on low voltage level. The product is
usable for IT-grid only.
2.2 Principle of the Product
The product can feed, power controlled, the energy stored in batteries into the grid. For
this purpose it converts the DC voltage of the batteries into grid-frequent AC voltage. If
required, reactive power can be provided. To charge the batteries from the grid the
inverter operates as a controlled rectifier.
The control card (-A1; -A2) controls the power semiconductors and for that the AC side
and DC side currents and voltages and measures the temperatures of the power
semiconductors. The control card detects the positions of the AC circuit breaker and
the Enable switch. The communication with the control card is provided via the
Ethernet/EtherCAT-interfaces.
Figure 4 shows the schematic structure of the power unit. The connection of the
batteries is provided with copper busbars at the DC switch disconnector (-Q1). The DC
link voltage corresponds to the cut-in battery terminal voltage. The product transfers
energy from the grid into the DC link and vice versa.
