Patent ID: 7919887

Claim:
A high repetitious pulse generation and energy recovery system comprising: a bridge circuit including a first switch connected at one side to a cathode of a first diode at a first bridge circuit contact point (B), a second switch connected at one side to an anode of a second diode at a second bridge circuit contact point (D), a first bridge circuit terminal point (A) connecting the other side of the first switch and a cathode of the second diode, and a second bridge circuit terminal point (D) connecting the other side of the second switch and an anode of the first diode, wherein both of the first and the second diodes allow electric current to flow from the second bridge circuit terminal point (C) to the first bridge circuit terminal point (A) when the first and the second switches are both on; a capacitor capable of holding electric charge connected between the first and the second contact points (B, D) of the bridge circuit; an inductive load operatively coupled to the first and the second bridge circuit terminal points (A, C); and a control circuit for controlling the first and the second switches to turn on and off simultaneously; wherein the control circuit controls the first and the second switches to turn on for supplying a pulse electric current through the first switch to the first bridge circuit terminal point (B) at least for the duration of the time required to fully discharge the capacitor, wherein the electric current passes through both of the first and the second switches, through both of the first and the second diodes, and through the inductive load, whereby the diodes enter into a freewheeling state, and wherein the control circuit further controls the first and the second switches to turn off, thereby terminates the freewheeling state and restores the electric charge to the capacitor by recycling the discharged electric current from the inductive load through the first diode, whereby the system supplies a series of current pulses that are generated at least once per a second to the inductive load and recovers residual magnetic energy from the inductive load by recharging the capacitor so as to use the charge for a next discharge of the capacitor.
