Pulsed Power Generators

This chapter presents an overview of commonly used pulsed generators in bioelectrics. The concept of pulsed power is discussed in Sect. 15.1. One of the key components of ultrashort pulse generator is the switch that is capable of closing in time of nanoseconds or subnanoseconds. A variety of switches, including gas spark gap switches and MOSFETs, can be used (Sect. 15.2). Besides the switches, the circuits that are often used in producing ultrashort pulses are discussed in Sect. 15.3. Finally, when ultra-high voltage pulses are needed, an air-core transformer or a Marx generator can be used, which are discussed in Sect. 15.4.
