IC697PWR748D Analogue conversion function

IC697PWR748D shows the analogue power circuit diagram and Figure 13 shows the analogue voltage source inverter Simulink model diagram.IC697PWR748D shows the LCL filter as well as the Simulink conversion function pathway for the utility grid. Because it is perceptible, it is difficult to track the signals at different nodes on the board, especially if the board complexity is high, the difficulty is more obvious.

IC697PWR748D Building a circuit with PLECS is very simple and straightforward. Simply drag and drop the required components together and connect them to make the desired circuit board. The PV system simulation module using PLECS is the same as the one represented in Figure 4, except that the device subsystem is changed using the PLECS toolbox and the control method is the same as that depicted in Figure 7. The device subsystem is the circuit modelled with PLECS. The board includes models of the DC power supply, inverters, LCL filters and the utility grid.

The detailed power board model of the IC697PWR748D comprises the subsystem described below.The DC power supply is built using voltage sources. The inverter is built based on four IGBTs and built-in antiparallel diodes. These switches are controlled by gated signals (Sa-Sb-Sc-Sd), which are transferred from the Simulink control component to the PLECS circuit using special gated signal ports. The electronic ports are used in the input and output subsystems of the electronic signals (DC+, DC-, L, N).
