ABSTRACT:
A circuit and method for creating a high-power electrical pulse which has a smooth or flat-topped configuration as well as a very short rise time. A metal oxide varistor (MOV) is preferably placed in parallel with a load and a switch is preferably placed in series between the MOV and the load.
