Development of 5 kW single-phase non-isolated inverter
Aiming at the weaker suppression ability of grid-connected inverters with traditional PI and proportional resonance PR control, a single-phase grid-connected inverter control scheme based on quasi-PR control strategy is proposed. A small-scale, low-cost single-phase non-isolated 5 kW inverter that c...

description | Aiming at the weaker suppression ability of grid-connected inverters with traditional PI and proportional resonance PR control, a single-phase grid-connected inverter control scheme based on quasi-PR control strategy is proposed. A small-scale, low-cost single-phase non-isolated 5 kW inverter that can be used for large-scale power supply at home has been simulated and connected to the grid. The design principle of the inverter is expounded from two aspects of hardware and software. The simulation analysis is carried out by using the S-Function function in Matlab software. The control strategy is based on quasi-PR control and compared with the traditional PI and PR controllers. Based on the simulation, the experimental verification is carried out with an experimental prototype. The research results show that the proposed quasi-PR control strategy has great advantages compared with PI and PR control in eliminating steady-state error, improving grid-side current quality and resisting grid interference. Not only can it be better to achieve no static control, but also has scalability. With the static-free characteristics of the quasi-PR controller, the single-phase non-isolated 5 kW inverter will have broad application prospects in the home power supply system. |
