Technical FAQs 4

Which microcontroller is best for a PV inverter?

The localized MPPT at each panel improves the performance of the system under partial shading and unmatched panel conditions. The Texas Instruments C2000 microcontroller family, with its enhanced peripheral set and optimized CPU core for control tasks, is ideal for controlling the power conversion. Figure 1. Grid Tied PV Inverter

How to control a PV micro inverter?

This section describes the details of software implementation of control of PV micro inverter. PV inverter control requires closed loop control of the DC-DC and DC-AC stage. PWM switching rates of the power stages are chosen such that only a single, fast 50-KHz ISR is needed for controlling the DC-DC flyback and the DC-AC inverter stage.

How does an inverter control system work?

2.1. Inverter Control Algorithm The inverter control system is designed to work while connected to or disconnected from the general power grid. If the grid does not supply an adequate AC voltage, the control system opens the breaker between the PS and the inverter output.

Which microcontroller is used in solar micro inverter kit?

All of the key functions are implemented on the F28035 MCU for the Solar Micro Inverter kit. A C2000 piccolo microcontroller with its on-chip PWM, ADC, and analog comparator modules can implement complete digital control of a micro inverter system. Figure 4 shows a simplified diagram of different stages present on the Solar Micro Inverter kit.
