BACKGROUND OF THE INVENTIONMagnetic stimulator systems have a wide range of medical applications, including transdermal nerve stimulation. In many cases a monophasic stimulus is desired, in which each magnetic pulse in a pulse train has a rapid rise and a slow fall. In contrast, a pulse having similar rise and decay rates is referred to as being biphasic.
The general prior art approach for generating such pulses is illustrated in FIG. 1. A stimulus coil 12 acts as an inductance in the circuit 10, and the magnetic field at the coil 12, which is proportional to the coil current, is the output stimulus. A pre-charging power supply 14 charges a capacitor C to a predetermined voltage. A switch S1 is used to connect the coil 12 across the capacitor C, causing an LC oscil...
