Usually installed under the PV panel, micro inverter is required to have high power conversion efficiency, good thermal performance, small size and long lifetime. The conventional auxiliary power supply is usually a Flyback, either secondary side regulated (SSR) or primary side regulated (PSR).
The recommended maximum load current capability is 2 A, which is also enough for the auxiliary power of micro inverter which usually does not exceed 10 W power need. The Fly-BuckTM is also known as the isolated buck converter, where the isolated output is generated by adding a coupled winding to the filter inductor of a buck converter.
This requires the auxiliary bias supply, which takes power from the PV panel, to be able to produce both the non-isolated low voltage bias voltages for the DSP and signal acquisition circuit, and the isolate bias voltages for the inverter gate drivers' use. Figure 1-4 shows a typical power tree of micro inverter. Figure 1-4.
Solar Micro Inverter is able to help the solar photovoltaic PV system to achieve per-panel level Maximum Power Point Tracking (MPPT) to improve power yield performance even in unideal conditions such as cloud or tree shades or bird drops and dust on the PV panels.
It operates efficiently across a wide input voltage range, typically from 250V to 1000V, accommodating DC link voltage variations. To enhance the overall reliability of your power converter system, our auxiliary power supply features a simple topology and a low component count, ensuring robust performance and ease of integration.
