Neutral Beam Heating Injector of 1 MW beam power for the TCV tokamak (Lausanne, Switzerland) was developed in BINP. The plasma is formed in a plasma box with inductively coupled RF power at frequency about 4 MHz. Required RF power in the plasma box is up to 40 kW during the period of 2 seconds with 5 minutes intervals. Solid state RF generator with such capability has been developed in BINP. The generator has a modular structure with combining RF power of 16 identical modules. Output RF power of the generator is regulated by DC power supply voltage. At present Injector is working at TCV. Description of the RF generator design, main features and the test results are presented in the report.
