Description

This reference design is a solar power optimizer, which can support up to 80V input voltage and 80V output voltage, providing upwards of 18A output current and input current. The design uses a configurable four switch buck-boost converter to step up or step down the panel current to the string current. The bypass circuit uses a smart diode controller-based design.

This reference design includes power line communication (PLC) and also features wireless communication. Both the digital control and communication are all implemented in a single C2000™ microcontroller (MCU).
