Flyback type inverter for small scale photovoltaic power system
Description
This paper presents a newly developed flyback type inverter for a small scale (low power) photovoltaic power system and a maximum power point tracking (MPPT) controller without a current sensor for this system. As the small scale photovoltaic power systems are used in parallel, cost reduction with high reliability is strongly required. In the proposed inverter, the current is controlled with open loop, and then the generated power of photovoltaic array is calculated by an equation using the voltage of the photovoltaic array. Therefore, the system can obtain the power by detecting only the voltage of the photovoltaic array. As a result, we may obtain the performance of the MPPT without a current sensor as well as with a current sensor.
