1. A neuromodulation system, comprising:
an external free running resonance magnetic field generator, comprising:
a housing;
a coil;
a capacitor connected in parallel with the coil such that a stimulation signal is a portion in time of a resonance between the parallel capacitor and coil;
a DC power supply at a first side of the parallel capacitor and coil, and configured to activate the parallel coil and capacitor; and
a switch to ground on a second side of the parallel capacitor and coil, wherein the switch comprises a microprocessor, a transistor and a rectifier;
wherein the microprocessor is configured to turn off a gate or a base of the transistor just prior to a first series of decaying resonant pulses to provide a free running resonance between the coil and the capacitor and then turn on the gate or the base to build up a current in the magnetic field generator prior to a second series of decaying resonant pulses to reduce electrical energy in the coil between the first and second series.
