Rectifier system with inverter

 

A battery system is connected to two systems in parallel –

the rectifier and the inverter system. The rectifier system supplies the direct current (DC) devices in case of a power failure. If the mains supply is available, the rectifier system charges the batteries with the appropriate voltage, controlled by a control and monitoring unit.

 

The inverter system is connected to the batteries as a special DC device. Its alternating current (AC)output supplies important AC devices whose function must also be maintained in case of a power failure. These are normally supplied with alternating current from the power grid – in case of a power failure, the batteries and inverter system take over.

 

The rectifier system ensures a reliable supply of direct current devices that must continue to fulfil their function even in case of a power failure. Safe supply is ensured by rectifier modules with redundant design, i.e. more modules are connected in parallel than required, so that the function of the DC supply is maintained even in case of failure of individual rectifier modules.
