Latest Patents

Mingshen Li holds a patent for a "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 is composed of outer loop power droop control, voltage feed-forward quasi-resonant control, and inner current loop dead-beat control. This innovative approach raises the response speed of the inverter and inhibits the influence caused by load fluctuations in a micro-grid. Furthermore, the grid-connected steady state control introduces phase lead control to the power droop control, ensuring that the output voltage of the inverter is always slightly ahead of the power grid voltage. This design avoids the energy pour backward phenomenon of the inverter due to phase errors, thereby achieving stable and reliable operation in grid-connected mode.
