Description

technical field [0001] The invention relates to a radio frequency power supply, in particular to a high-power all-solid-state radio frequency power supply based on a MOS-FET amplifier. Background technique [0002] At present, the RF power supply products in the domestic market include domestic traditional tube RF power supplies and imported all-solid-state RF power supplies (such as AE, ENI, COMDEL and other foreign companies). The market share of imported solid-state RF power supplies has grown rapidly, with an annual growth rate of about 40% in the past two years, mainly as agents in China. [0003] The RF power supply technology traditionally used in China is based on the self-excitation of ceramic electronic tubes. The ceramic tube has a short working life (usually 1200 hours, and the RF tube needs to be replaced regularly), and the continuous working time is short (usually 4 to 8 hours). Power frequency Unstable, large power fluctuations, low efficiency (about 50%), a...
