A Bipolar Modular Multilevel Generator Based on Half-Bridge and Special Full-Bridge for Electroporation Applications

High-Voltage Pulse Generators for Electroporation Applications: A Systematic Review

“…Because the number of switches is a significant index of the overall structure, an increase in switches means an increase in driving circuits, protection circuits, and control signals, that leading to a larger and more complex whole structure. The topology presented in [88] is consisting of a special FB module and several HB modules, as shown in Fig. 32.…”

A Flexible Solid-State Marx Modulator Module Based on Discrete Magnetic Coupling Drivers

“…Due to the magnetic core, LTD has low efficiency, a large volume, and an output pulse width constrained by the magnetic core characteristics [8]. SSPPM suffers from poor regulation accuracy due to charging voltage imbalances caused by transformer core differences [9]. MMC has modularized redundant scalability hardware features but also obvious drawbacks.…”

“…At present, commercially isolated DC-DC [15] converters, high-frequency isolation [16] transformers diode strings [28] and air-isolation modules [29] are the main isolated power supply methods. Miniaturization is the prevailing development trend of pulse generators [30] but numerous trigger optical fibers dispersed in space and the requisite isolated power supply impair space utilization and impede system integration, and fiber optic transceivers are more expensive [9,15,[17][18][19]. Although some researchers have employed a self-triggered driver in Marx generators [25,26], it has certain constraints on capacitor charging voltage, and a self-triggered driver cannot control each semiconductor switch independently, which results in a long output pulse tail and a single pulse waveform.…”
