Abstract: The pulse adding has been used in super-large pulsed power machines in order to achieve extremely high output power by overcoming the physical limitations of a single pulsed power generator. The inductive voltage adding is an effective way to improve the system flexibility, compactness, and easiness of maintenance. The linear transformer driver (LTD) is a relatively new technology of pulsed power generation based on the concept of pulse adding. In addition, solid-state LTD has further extended this technology to smart pulsed power by introducing the functions of arbitrary waveform synthesis and logical response to the load behavior.
