摘要：
A PV pumping system using induction machine is thoroughly investigated in this work. The power structure is constituted of multiple parallel DC/DC step-up converters directly connected to the inverter. Each DC/DC converter is used as a DC current transformer. The input characteristic of the inverter is enforced by means of an appropriate regulation, in order to avoid problematic dynamic resistance. The system is simulated under Matlab / Simulink and it has been shown that the proposed regulation scheme is unconditionally stable.
