The UPS is connected between the public utility's mains and 
the loads to be protected. 
The power section of the rectifier converts the mains voltage 
to DC voltage for supplying the inverter. The circuit 
technology used (PFC) enables sinusoidal current 
consumption and therefore operation with little system 
disturbance. A separate, second rectifier (charging REC set 
up using switch mode power supply technology) is 
responsible for charging or trickle-charging the battery 
connected in the intermediate circuit. The configuration of this 
charging REC means the harmonic content of the charging 
current for the battery is almost zero, so the service life of the 
battery is increased even more. The inverter is responsible for 
converting the DC voltage into a sinusoidal output voltage. A 
microprocessor-controlled control system based on pulse-
width modulation (PWM) in conjunction with digital signal 
processor technology and extremely quickly pulsating IGBT 
power semiconductors of the inverter guarantee that the
