A review on topology and control strategies of high-power inverters
A comprehensive analysis of high-power multilevel inverter topologies within solar PV systems is presented herein. Subsequently, an exhaustive examination of the control methods and
As introduced in Chap. 1, the photovoltaic (PV) inverters are the key link responsible for converting solar energy into electricity. The topology and control technology directly determine the investment costs, conversion efficiency, and output performance of the PV generation system. There are many topologies for connecting PV modules to the grid.
Although various intelligent technologies have been used in a PV inverter system, the intelligence of the whole system is still at a rather low level. The intelligent methods are mainly utilized together with the traditional controllers to improve the system control speed and reliability.
Configuration of PV Inverters ]. Among them, the most commonly used configurations are the series or parallel and series connections. If the PV panels are attached in series with each other it is called a string, and if these are then connected parallel it forms an array. Basically, the PV modules are arranged in four ].
Stage 1, stage 2, and stage 3 form the typically cascaded control structure. It should be noted that the power, DC voltage, and AC current are the basic control objectives for the commonly used PV inverter, which merely satisfy the basic normal operation requirements.
