[IEEE 2019 22nd International Conference on Electrical Machines and Systems (ICEMS) - Harbin, China (2019.8.11-2019.8.14)] 2019 22nd International Conference on Electrical Machines and Systems (ICEMS) - Control and Modulation Method of a Three-phase Eight-switch Inverter for Two-stage Grid-connected Photovoltaic Systems
摘要： A novel transformerless two-stage photovoltaic (PV) grid-connected inverter is introduced in this paper. The system is composed of three-level boost (TL-Boost) DC/DC circuit and three-phase T-type eight-switch DC/AC topology. By using the multiloop interleaved control strategy and adjusting the conduction time of power switch phase of the first-stage boost DC/DC part, the inductor current ripple is reduced and the balance of DC bus capacitor voltage could be achieved respectively. Meanwhile, a nine-vector space vector pulse width modulation (SVPWM) algorithm based on optimal five-stage is adopted for eight-switch DC/AC inverter circuit, which could simplify the algebraic operation, reduce the switching loss and improve the utilization of the DC bus voltage. Finally, a 10kW experimental platform is built to verify the validity and effectiveness of the proposed control and modulation method.

[IEEE 2019 IEEE 16th International Conference on Smart Cities: Improving Quality of Life Using ICT & IoT and AI (HONET-ICT) - Charlotte, NC, USA (2019.10.6-2019.10.9)] 2019 IEEE 16th International Conference on Smart Cities: Improving Quality of Life Using ICT & IoT and AI (HONET-ICT) - Novel Direct Power Control Strategy for Single-Phase Photovoltaic Inverters
摘要： In the design of inverter controllers, a phase-locked loop (PLL) is usually used to synchronize the inverter output with power grids. However, the adoption of PLL may increase the complexity of the controller. In addition, the accuracy of the PLL can be impacted if the power quality of the power grid is distorted, and the inaccurate PLL output can degrade the performance of the controller. To overcome these issues, a number of non-PLL control strategies have been studied for the single-phase PV inverter. In this work, a novel non-PLL direct power control strategy (DPC) for single-phase H-bridge SVPWM photovoltaic (PV) inverters are proposed. In this strategy, instantaneous real and reactive power are calculated respectively by using voltage and current components with specific frequencies. Then a maximum power point tracker (MPPT) technique is integrated with the strategy to maximize PV generation. Simulation results demonstrate the effectiveness of the proposed strategy.
