A modular solid‐state pulse generator based on a multi‐turn linear transformer driver (LTD) is designed for the application of pulse power techniques with a high voltage, large current and wide pulse width. The LTD adopts the method of multi‐turn winding on the magnetic core, which can help to output pulses of wide width. The isolation of the power supply with windings in the same direction of the LTD modules is designed, and the isolation voltage of the magnetic cores is the working voltage of the LTD modules. A modular solid‐state pulse generator based on the multi‐turn LTD is developed, which is composed of 10 LTD modules. Each module consists of 18 energy storage capacitors, metal‐oxide‐semiconductor field‐effect transistors and their driving circuits connected in parallel. The pulse generator can output pulses with parameters including a voltage ranging from 0 to 5000 V, a pulse current up to −500 A, and a pulse width ranging from 200 ns to 5 μs. When all modules work in synchronisation, rectangular pulses can be produced with a rise time of 30 ns and a fall time of 16 ns. If all modules are asynchronised, trapezoidal pulses are produced with adjustable step‐like rising and falling edges. Moreover, a higher‐voltage pulse can be achieved by increasing the number of LTD modules.
