A scalable, interleaved pulse forming converter is disclosed having two Buck switching converter modules each contributing half to the total load of the circuit to produce a programmable current pulse. Synchronization pulses to the two modules are set 180 degrees out of phase of each other to reduce ripple current. The invention is susceptible to various interleaved modifications to further reduce ripple current and increase power, as well as to electrically isolate the load from input or battery ground.
