| Abstract |
The control strategy that regulates the phase and
the amplitude of the output voltage according to output active
power and reactive power respectively is adopted generally in
inverter parallel techniques. However, active power and
reactive power are related to both voltage amplitude and voltage
phase. This paper deduces the output impedance of the inverter
and discusses the relationship between active power, reactive
power and amplitude and phase of output voltage. The decouple
control strategy can be realized through circuit parameters
design. The influence of component’s tolerance on output
voltage is discussed. Then a simplified load-sharing control
strategy based on phase-synchronization and amplituderegulation
of reference voltage is proposed and the model of
parallel system is established. Performance of a parallel system
is analyzed and experimental results are given. |
