 Abstract

This paper presents a current sensorless maximum power point tracking (MPPT) control method for dual-mode photovoltaic(PV) module-type interleaved flyback inverters (ILFIs). This system, called the MIC (Module Integrated Converter), has beenrecently studied in small PV power generation systems. Because the MIC is an inverter connected to one or two PV arrays, thepower system is not affected by problems with other inverters. However, since the each PV array requires an inverter, there is adisadvantage that the initial installation cost is increased. To overcome this disadvantage, this paper uses a flyback invertertopology. A flyback inverter topology has an advantage in terms of cost because it uses fewer parts than the other transformerinverter topologies. The MPPT control method is essential in PV power generation systems. For the MPPT control method,expensive dc voltage and current sensors are used in the MIC system. In this paper, a MPPT control method without currentsensor where the input current is calculated by a simple equation is proposed. This paper also deals with dual-mode control. Simulations and experiments are carried out to verify the performance and effectiveness of the proposed current sensorlessMPPT control method on a 110 [W] prototype.
