The UPS is connected between the public network and the 
power load segments to be protected. 
The rectifier is powered from the mains and converts the AC 
voltage into a stabilized DC voltage to feed the inverter. The 
circuitry technology used (PFC) enables sinusoidal current 
consumption, thus allowing a low circuit feedback operation. A 
separate, second rectifier (charger) based on switching power 
supply technology recharges or maintains the charge of the 
battery in the intermediate circuit. Due to the special circuitry 
technology used in this charger

 

/ rectifier, the harmonics of the 

charging current are reduced significantly. Additionally, a sleep 
mode considerably increases the service life of the battery. The 
inverter converts the DC voltage into a sinusoidal AC voltage. In 
combination with digital signal processor technology and 
extremely high pulse rate IGBT-power semiconductors in the 
inverter, a microprocessor-controlled regulator on the basis of 
pulse-width modulation (PWM) guarantees a voltage system of 
highest quality and availability on the secured busbar. 

 

 

In the event of mains problems (e.g. power outages), power is 
supplied to the load segment without any interruption from the 
inverter, which now uses the battery. Since no switching is 
required, the load segment experiences no power supply 
interruption at all.
