In October 2016, Kingser developed the semiconductor no-arc device with tiny size and perfect performance. It marked a milestone of electronic arc extinguishing technology.
 
In February 2017, Kingser developed the no driving blind area thyristor drive device. It can greatly reduce (or eliminate) the driving-blind-area and harmonic pollution caused by the traditional thyristor drive technology.
 
In the same year, the DDS(T) series of dynamic drive devices integrating thyristor and driving function were introduced, which solved the problems of harmonics and inconvenience in thyristor triggering.
 
In November 2017, we developed the active electronic arc extinguishing device, to meet the arc extinguishing requirements of high-voltage and high-current DC relays (contactors).
 
We further developed the VDC high-voltage DC relay (contactor) in 2018, which uses the air convection type contact switch structure and high performance magnetic blow-out system. It's applicable to the field of new energy such as hybrid vehicles, full battery electric vehicles, fuel cell cars and vehicle charging systems.
