【Abstract】 High- voltage power supply (HVPS) is one of the most important components in ECRH (Electron Cyclotron Resonance Heating). It is the power supply of the gyrotron, which generate microwave to heat the plasma in TOKAMAK. The composing and principle of high- voltage power supply is analyzed in this paper. The circuit of every links of the system, include the main circuit, grid drive circuit, pulse gate circuit et al, and a new PI adjuster with forward feed- in are designed. Parameters of adjuster are fixed based on MATLAB simulation. The experiment based on the parameters shows better characteristics.更多还原
