  5. UPS Terms • UPS Terms • THD • Crest Factor • Power Factor Correction (PFC) • Buck/Boost • Modified Sine Wave/True Sine Wave • Transfer Time • Battery Terms • Float • Equalization • Constant Current Charging • Constant Voltage Charging • VRLA

  6. UPS Technologies Line Interactive • 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)

  7. UPS Technologies Line Interactive: Modified Sine Wave • 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.

  8. 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

  10. UPS Technologies Dual Conversion Online UPS • Zero Transfer Time • Always: • Isolates the Load From the Input AC • Rectifies the Input AC • Power Factor Corrects to Unity: pf=1 • Generates A True Sine Wave Output With the Inverter • Supplies Regulated & Isolated Voltage To the Load • Synchronizes to the Input Phase When Online

  11. Dual Conversion On-Line UPS System

  12. Dual Conversion Key Components • General Block Diagram

  13. Dual Conversion Key Components • Inverter & Output Filter • Insulated Gate Bipolar Transistors • Unipolar PWM Waveform Generation • Filtering For True Sine Wave Output

  14. Dual Conversion Waveforms • PWM Generation & Resulting IGBT Output • Unipolar PWM Wave Generator • Modulates a Reference Sinewave With a Triangle Carrier Wave. • Triangle Wave Frequency around 22kHz (Above Audible Range). • Less Harmonic Power to Filter, Greater Efficiency, Smaller Size

  15. Dual Conversion Output Waveforms • 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.
