Load sharing for parallel single-phase inverters
Parallel single-phase inverters are widely used in uninterruptable power supply (UPS) and distributed renewable energy generation to improve reliability and flexibility. Each inverter is required to share equal output current for any load condition (including linear and non-linear load). This di...

| description |
Parallel single-phase inverters are widely used in uninterruptable power supply (UPS)
and distributed renewable energy generation to improve reliability and flexibility.
Each inverter is required to share equal output current for any load condition
(including linear and non-linear load).
This dissertation focuses on the study of SPWM voltage source inverters without any
interconnection lines. Control scheme for parallel operation of two single-phase
inverters with separate DC bus will be studied and designed.
A set of effective mathematical models and analyzing methods on parallel inverter
system are developed. According to the strategy of load-sharing and operating
characteristics, droop control and voltage current double closed-loop control are
finally used to complete the parallel operation of two single-phase inverters. |
