The inverter is initially tested in the open-loop configuration with a resistive load for debugging, and the issues with ringing in the gate driver circuitry are resolved. Then, the inverter is tested using a grid simulator, which emulates the grid source voltage of 120 V at 60 Hz.
With the input PV power obtained from the irradiance and temperature data, the average inverter loss model can be used to measure the junction and heat sink temperatures of the DC-DC converter and H-bridge inverter. The inverter model also includes an efficiency block after the PV power production stage to account for the power losses.
Efficiency and losses, as well as the mean time between failures and inverter prices, are the three most crucial metrics for assessing inverter technological advancements. High dependability, a long life, and lower costs are all correlated with high integration levels.
With this in mind, this report showcases and describes an approach to help assess and predict the reliability of PV inverters. To predict reliability, thermal cycling is considered as a prominent stressor in the inverter system.
The thermal model of the inverter is implemented using the data obtained from the data sheets entered in the form of variables, parameters, and lookup tables. Figure 16 shows the thermal model of a generic H-bridge-based PV inverter with current source at the input and AC grid voltage source at the output connected through an inductor filter.
The switching model of the inverter contains the electrical models of the switches along with the topology of the power converter, passive components, electrical model of a PV panel, and the closed-loop control for a grid-controlled inverter and maximum power point tracking of the inverter.
