Latest Patents

Leming Zhou holds a patent titled "Phased lock loop control for multiple inverters connected to a polyphase grid." This invention presents a steady state control method for a three-phase double-mode inverter. The off-grid steady state control comprises outer loop power droop control, voltage feed-forward quasi-resonant control, and inner current loop dead-beat control. This innovative approach increases the response speed of the inverter and mitigates the impact of load fluctuations in a micro-grid. Furthermore, the grid-connected steady state control incorporates phase lead control into the power droop control, ensuring that the output voltage of the inverter remains slightly ahead of the power grid voltage. This design prevents the energy pour backward phenomenon due to phase errors, enabling stable and reliable operation in grid-connected mode.
