High voltage regulating frequency AC power supply based on CAN bus communication control

High voltage high frequency AC power supply (HVHFACPS) is widely used in military, industry, scientific research and so on. Different applications ask for different functions, such as the control modes selectable, work modes selectable, output voltage adjustable, frequency adjustable, and even the integratability and expandability. In this paper, a kind of HVHFACPS is introduced, which output voltage can be regulated from 0 to 30 kV and output frequency can be regulated from 1kHz to 50kHz. There are continuous and discontinuous work modes to be chosen for a continuous AC voltage output or a discontinuous output and the work time and frequency can be regulate in the discontinuous work mode. There are remote and local control modes to be chosen for a remote control by computer or a local control by the keyboard on the cabinet panel. The control system of this power supply has the CAN bus communication function so that it can be connected to the CAN bus network and work cooperate to other equipments. Some experiments such as dielectric barrier discharge (DBD) and plasma generation are carried on use the power supply and the results proved that the functions are realized and the performance is good.
