  • Electron beam systems
    Patent number: 7692390
    Abstract: A high-power amplifier having a current-adding array is provided for high-speed driving of an inductive element, e.g., a deflection coil of an electron beam gun. The amplifier includes a first voltage node (U1) and a second voltage node (UV), at least one of which is connected to a regulated power supply, and a plurality of first switchable bridges (B11, B12, B13, . . . , B1k) connected in parallel between the first and second voltage nodes. Each switchable bridge includes at least one resistor (R11, R12, R13, . . . , R1k) with a resistance value that is selected so that a first resistor (R11) has a first resistance value WR11 equal to Rmin, a second resistor (R12) has a second resistance value WR12 greater than or equal to WR11 and an n-th resistor has an n-th resistance value WR1n greater than or equal to WR1n?1.
