Pulsed power technology has been widely used in industrial and biomedical applications. In many cases, high-voltage pulses with current amplitudes up to hundreds of amperes are required. Although solid-state Marx generators have been studied for a couple of years, the rated current of power semiconductor switches such as IGBT and MOSFET in Direct Insertion Packaging (DIP) is usually much lower than 100 A, which cannot meet the high-current requirements for low-impedance load. Therefore, two topologies of the multiple Marx generators in parallel are proposed to increase the amplitudes of output current. In the first structure, multiple Marx generators are connected in parallel directly. In the second structure, multiple Marx generators sharing a series of charging switches are connected in parallel. An FPGA provides two control signals for charging and discharging. Using many transformers with their primary winding in series, synchronous driving signals with negative bias voltage are realized. And the main circuit adopts the solid-state rectangular Marx circuit based on half-bridge units. Power IGBTs which has fast opening speed and high current capacity are utilized as the main switches. The experimental results show that the pulse generator with six 16-stage Marx generators directly connected in parallel can output high-voltage rectangular pulses with voltage amplitude up to 10 kV and peak current up to 300 A through a 30 Ω resistive load at a repetition frequency of 100 Hz. The peak output current of six 4-stage Marx generators in parallel with shared charging switches can reach 300 A with a rising time of 230 ns, and the maximum output current can reach 460 A with a rising time of 272 ns through a 5 Ω resistive load. The results show that the parallel connection of multiple Marx generators can effectively reduce the internal resistance of the system and improve the current capacity of the system. Moreover, multiple Marx generators in parallel with shared charging switches not only output high-current pulses, but also halve the number of switches while the EMC is also improved. The current balancing can be further improved by inserting the parallel connection between stages.
