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.
