This C2000 MCU based MPPT solar DC-DC reference design uses an isolated DC-DC stage as is shown in Fig 1. It consists of two DC-DC stages. These are, (1) a 2-ph interleaved boost converter and, (2) an isolated half bridge LLC resonant converter.
The hardware design includes the minimum system of STC89C52 MCU, sunlight signal acquisition circuit, A/D conversion circuit, key circuit, motor drive circuit, etc. The software is written in C language, including main program, data acquisition subroutine, key reading subroutine, data comparison subroutine, etc.
Figure 8. In a micro solar inverter, we need auxiliary power that can output multiple voltages to A/D sample circuits, drive circuits, MCU controller, and so forth. On the other hand, the auxiliary power must be completely isolated from primary side to secondary side.
Energy Utilization and Smart Grids Citation Kun Huang 2020 IOP Conf. Ser.: Mater. Sci. Eng. 782 032119 DOI 10.1088/1757-899X/782/3/032119 This paper designs a solar energy automatic tracking system based on STC89C52. The photoelectric sensor collects the sunlight signal. After A/D conversion, the collected signal is sent to STC89C52.
Isolated MPPT Solar DC-DC Converter Block Diagram The DC-DC converter draws dc current from the PV panel such that the panel operates at its maximum power transfer point. This requires maintaining the panel output, i.e., the DC-DC converter input at a level determined by the MPPT algorithm.
There is one MPPT module to capture maximum energy from the PV panel. This type of topology is called “string inverters” just like Figure 5(b); its main feature is: Each string branch has its own inverter enabling better MPPT. The strings can have different orientations.
