Figure 8 Power circuit with mains supply
The rectifier is powered from the mains and converts the AC voltage
statically into a stabilised DC voltage. This DC voltage serves for
charging and automatic trickle charging of the connected battery,
which is always charged as a result.
The inverter converts this secured DC voltage into a stabilised
sinusoidal AC voltage and powers the connected loads.
