Design of Parallel Interleaved-Phase-Shift-PWM Inverters with Voltage Feedback Control

Abstract:

The paper is to design and implement parallel operation of paralleled inverters with interleaved phase shift. For parallel operation, one inverter is used as master module to transmit synchronization signals to trigger the external interrupts of two microcontrollers for synchronous operation to slave module. In this paper, the design of voltage controlled loop feedback controller by proportional-integral controller is employed to have fast transient response with different load conditions. It is proposed that interleaved phase shift for parallel inverters could reduce output voltage ripple of inverter and increase the system response. The experimental results show that the proposed inverter provided a voltage output with low harmonic distortion by the proposed interleaving phase-shift parallel inverter scheme.
