Switched inductor is the combination of a pair of equal valued inductors and multiple passive (diodes) elements. Thus, this switched inductor concept is added to the transformerless boost inverter so that it has characteristics of high gain, high efficiency, high integration, few power devices, less switching losses and easy to control.
Currently, however, the suppression of circulating current and output current ripple individually results in an evident increase in the number and volume of inductors. In this work, an inductor integration scheme is developed to improve the IPS inverter. Two integrated inductors are developed for different application configurations.
For a grid-connected PV system, inverters are the crucial part required to convert dc power from solar arrays to ac power transported into the power grid. The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability .
The boost inverter can be derived from a boost converter and a full bridge inverter by multiplexing the switch of basic boost converter. On boost converter side, the dc boost inductor is replaced by a switched inductor concept which can increase the output voltage and hence gain & efficiency.
Two integrated inductors are developed for different application configurations. As a result, the circulating current and output current ripple are simultaneously suppressed by an integrated inductor, making each phase of the IPS inverter to be equipped with only one integrated inductor implemented by wounding two coils on one magnetic core.
Figure 12 shows the control of the PV inverters with ANN, in which the internal current control loop is realized by a neural network. The current reference is generated by an external power loop, and the ANN controller adjusts the actual feedback current to follow the reference current. Figure 12.
