Pulsed plasma frequency of 200kHz achieved using the high frequency characteristics of SiC 1kW Output
Submerged Pulse Plasma Generator1kW Output Desktop MPP-HV04SiC

Overview

Enables a pulsed plasma frequency of 200kHz by adopting an SiC power device module.　

Results

Controlling the chemical reaction of the plasma requires manipulation of pulses in the sub-μ to several μs range. Leveraging the capabilities of SiC makes it possible to achieve consistent ultra-short plasma pulses in the sub-μ region that was difficult with Si IGBTs.
