To supply the cathode voltage for the two gyrotrons (140 GHz/1 MW/3 s) of the electron cyclotron resonant heating system on HL-2A, a high-voltage power supply (HVPS) based on pulse step modulator (PSM ...

High-level noise represents a risk for health, thus an important trouble to handle. For low frequency noise generally it is employing an Active Noise Control (ANC) system. ANC systems operate ...
