Patent ID: 7218501

Claim:
An electrical shock circuit for an electrical discharge weapon comprising: a battery source; an inverter transformer having a primary coil of the inverter transformer connected between a first pad and a second pad and a secondary coil of the inverter transformer connected between a third pad and a fourth pad; an oscillation capacitor connected between the first pad and the second pad; an independent oscillator; a switch connected between the inverter transformer and a common voltage node, the switch being also connected to the independent oscillator; and a full wave rectifier connected with the secondary coil of the inverter transformer via the third pad and the fourth pad, wherein the independent oscillator triggers the switch to supply an energy from the battery source to the primary coil of the inverter transformer, wherein the primary coil of the inverter transformer oscillates the energy with the oscillation capacitor at a resonate frequency for a full cycle of the energy, wherein the full cycle of the energy has first and second half cycles, and wherein the first and second half cycles have substantially the same amplitude.
