Abstract
A magnetic stimulator of neuro-muscular tissue has a discharge capacitor, at least one discharge control switch for allowing discharge of the discharge capacitor into a stimulating coil and a circuit for recovering energy from the stimulating coil when current flow from the discharge capacitor to the stimulating coil is interrupted, the energy being recovered either by the discharge capacitor or a capacitor additional to the discharge capacitor. The additional capacitor may be a reservoir capacitor connected for charging by a power supply and there may be a circuit for pumping charge from the reservoir capacitor to a transfer capacitor and for pumping charge from the transfer capacitor to the discharge capacitor.
