Latest Patents

One of Niu's latest patents is for a static reactive power compensating equipment. This invention includes a circuit designed to prevent harmonic currents generated by adjusting lag compensation current from phase control from flowing out of the equipment. The design features a first reactor and a controller connected to a switching circuit, along with a second reactor that is connected between an output terminal and a connection node. The resonant circuit, which includes a third reactor connected in series with a capacitor, is constructed to resonate at a predetermined frequency, effectively absorbing harmonic currents flowing from the static reactive power compensating equipment.

Another significant patent by Niu is an output control apparatus for a microwave oven. This invention innovatively places a control switch in the secondary side of the power transformer, either in a magnetron circuit or in a rectifier circuit. The control switch is actuated by an on-off control signal, allowing it to open and close within zero-current time periods of a half-wave current. This design reduces transient rush current to the transformer and ensures reliable intermittent operation of the magnetron.
