Abstract: A pulse generator is disclosed that includes at least the following stages a driver stage, a transformer stage, a rectifier stage, and an output stage. The driver stage may include at least one solid state switch such as, for example, of one or more IGBTs and/or one or more MOSFETs. The driver stage may also have a stray inductance less than 1,000 nH. The transformer stage may be coupled with the driver stage and/or with a balance stage and may include one or more transformers. The rectifier stage may be coupled with the transformer stage and may have a stray inductance less than 1,000 nH. The output stage may be coupled with the rectifier stage. The output stage may output a signal pulse with a voltage greater than 2 kilovolts and a frequency greater than 5 kHz. In some embodiments, the output stage may be galvanically isolated from a reference potential.

Abstract: Systems and methods are discussed to create radiation from one or more compact toroids. Compact toroids can be created from plasma of gases within a confinement chamber using a plurality of coils of various densities of windings. High current pulses can be generated within the coil and switched at high frequencies to repeatedly generate compact toroids within the plasma. The plasma can produce radiation at various wavelengths that is focused toward a target or an intermediate focus.

Abstract: Embodiments of the invention provide IGBT circuit modules with increased efficiencies. These efficiencies can be realized in a number of ways. In some embodiments, the gate resistance and/or voltage can be minimized. In some embodiments, the IGBT circuit module can be switched using an isolated receiver such as a fiber optic receiver.
