The ZINVERT Intelligent High-Voltage Variable Frequency Drive (VFD) System is a next-generation high-to-high voltage source inverter independently developed by Guangzhou Zhiguang Electric Co., Ltd. (SZSE listed, stock code: 002169). Built on a cascaded power unit topology with phase-shifted SPWM control, the ZINVERT series delivers 3kV, 6kV, and 10kV output voltage directly — without a step-down output transformer — enabling precise variable-speed control of high-voltage AC motors across a broad operating range.
In power transmission and distribution networks, the massive integration of new energy sources—along with the widespread application of nonlinear and impact loads, such as high-capacity power electronic equipment—has given rise to serious power quality issues. The utilization of ZG-dSVG high-voltage dynamic reactive power compensation devices can significantly enhance power quality at the connection point between the load and the public power grid, for example, by Effectively improving the transient stability of grid voltage, improving the power factor, overcoming three-phase imbalance, eliminating voltage flicker and voltage fluctuations, and suppressing harmonic pollution,thereby comprehensively resolving power quality issues within industrial and power systems.
ZG-SPS (Intelligent Ship Shore Power System) is an intelligent high-voltage shore power solution designed for port ship berthing scenarios. Developed by Guangzhou Zhiguang Electric Technology Co., Ltd. through the inverter power supply as its core. It’s core function is to replace ship auxiliary engine power generation with shore-based clean electricity, achieving low-carbon, safe, and efficient port power supply. It is a key technical equipment for the green transformation of the shipping industry.
