He has made significant contributions to the field of power electronics, particularly in the development of uninterruptible power supply (UPS) systems and active power conditioners. With a total of 2 patents to his name, Wei's work showcases his commitment to advancing technology in energy management.
Latest Patents
Wei's latest patents include an innovative UPS system that features a function of parallel operation. This UPS system comprises one or more units with identical or varying capacities. The control circuit within the system is designed to manage a DC/AC inverter, utilizing both a voltage feedback control circuit and a current feedforward control circuit. The voltage feedback control circuit regulates the amplitude and waveform of the load voltage, while the current feedforward control circuit enables the inverter to function as a virtual fundamental resistor and a virtual harmonic resistor. This design allows each UPS unit to distribute output current based on the capacity ratio of the entire UPS system.
Another significant patent by Wei is the active power conditioner. This device includes multiple power electronic switch sets, along with input and output filters. The active power conditioner is capable of supplying a stable AC voltage to a load, even when voltage variations occur at the AC power source. This is achieved by controlling either the second or third power electronic switch set through high-frequency switching, while the remaining switch sets operate at low-frequency switching.
