Systems and techniques may generally be used for delivering pulsed electrostatic fields for therapeutic purposes. In one aspect, an electrostatic-field therapy apparatus may include a power source; a pulse-rate generator that may produce gating pulses; a solid-state switching stage with at least one transistor whose control terminal receives the gating pulses and whose conduction path periodically switches current from the power source; a step-up transformer whose primary winding couples to the switching stage and whose secondary winding may output high-potential pulses; an electrode coupled to the secondary winding; and a dielectric layer disposed over the electrode so that, when a body region is placed adjacent the dielectric layer, the high-potential pulses may be capacitively transferred through the dielectric as a therapeutic electrostatic field.
