Circuit providing a second parallel path for fast capacitor recharge

Claim 1

A SWITCHING DEVICE UTILIZING SEMI-CONDUCTIVE DEVICES OPERATIVE IN THE AVALANCHE MODE AND HAVING A CONDUCTIVE AND A NON-CONDUCTIVE STATE, COMPRISING A FIRST SEMI-CONDUCTIVE DEVICE OPERATIVE IN THE AVALANCHE MODE INCLUDING AN EMITTER, A BASE MEANS AND A COLLECTOR, A FIRST CIRCUIT FOR THE CURRENT FLOW OF SAID FIRST SEMI-CONDUCTING DEVICE OPERATIVELY CONNECTED BETWEEN SAID COLLECTOR AND SAID EMITTER AND INCLUDING, IN SERIES, A RESISTOR AND A VOLTAGE SOURCE, MEANS FOR NORMALLY MAINTAINING SAID FIRST SEMI-CONDUCTIVE DEVICE IN ONE OF SAID TWO STATES, INPUT MEANS OPERATIVE UPON APPLICATION OF A PREDETERMINED SIGNAL TO SWITCH SAID FIRST SEMI-CONDUCTIVE MEANS FROM SAID ONE TO THE OTHER STATE, CAPACITOR MEANS OPERATIVELY CONNECTED IN PARALLEL WITH SAID FIRST SEMICONDUCTIVE DEVICE AND HAVING A FIRST CHARGING CIRCUIT INCLUDING SAID RESISTOR, AND MEANS INCLUDING A SECOND SEMICONDUCTIVE DEVICE EFFECTIVELY FORMING A SECOND CHARGING CIRCUIT IN PARALLEL WITH SAID FIRST CHARGING CIRCUIT FOR CHARGING SAID CAPACITOR MEANS, AND MEANS OPERATIVELY CONNECTING SAID SECOND SEMI-CONDUCTIVE DEVICE WITH SAID FIRST SEMI-CONDUCTIVE DEVICE TO SWITCH SAID SECOND SEMICONDUCTIVE DEVICE FROM ONE OF SAID TWO STATES TO THE OTHER UPON SWITCHING OF SAID FIRST SEMI-CONDUCTIVE DEVICE.
