 Utility Supplies Power to Load Until Utility Failure
 2-4 ms Transfer Time
 Note: 16.7ms/Cycle at 60Hz
 Load Not Isolated From the Utility
 Utility Should Be Conditioned Surge Protection (Filtered & Surge Protected)
 Utility Should Be Voltage Regulated
 Buck & Boost
 “Modified Sine Wave” (PWM) or True Sine Wave
 Generally Smaller kVA Output (Less Than 3 kVA)

Modified Sine Wave Output When On Battery Supply
Output RMS Voltage Regulated By Pulse Width
Inverter Only Functions When Utility Has Failed
Should Provide Voltage Regulated, Filtered AC Utility to Loads Until
Utility Failure Occurs.
UPS Technologies
Line Interactive: True Sine Wave Output
 True Sine Wave Output At All Times
 Provides Voltage Regulated, Filtered AC Supply to Loads Until Power
Failure Occurs
 Inverter Operates When AC Supply has Failed
 CPU Always Synchronizing Inverter Phase with AC Supply Phase
 Bi-Directional Inverter Also Charges the Batteries.
 Inverter will maintain phase with AC supply

 Unfiltered Inverter Output & Filtered Output
 Output Filtering
 Eliminates the chop/step on the output waveform from the Inverter Circuit
 Ensures the current and voltage waveform stay in-phase for unbalanced loads.
