Converter-alternating current or direct current to alternating current, with continuously variable adjustment of output frequency and voltage

Claim 1

AN ELECTRIC POWER CONVERTER COMPRISING: A POWER INPUT COMPONENT HAVING PHASE-CONTROLLED GATING MEANS FOR TRANSMITTING A SUCCESSION OF DC OUTPUT PULSES; AN INVERTER COMPONENT INCLUDING MEANS TO RECEIVE SAID DC PULSES AND TO TRANSMIT THE SAME AS A SINUSOIDAL ALTERNATING CURRENT OUTPUT, AND GATING MEANS FOR CONTROLLING THE RECEPTION OF SAID PULSES; A FEEDBACK COMPONENT SENSING THE VOLTAGE OF THE POWER OUTPUT OF SAID INVERTER COMPONENT AND DELIVERING FEEDBACK SIGNALS VARYING IN ACCORDANCE WITH THE VARIATIONS OF POWER OUTPUT SENSED BY SAID FEEDBACK COMPONENT; AND A TRANSFER COMPONENT INCLUDING MEANS FOR GENERATING A SUCCESSION OF HALF CYCLES OF CONTROL VOLTAGE HAVING REPETITION INTERVALS SYNCHRONIZED TO THOSE OF SAID POWER INPUT COMPONENT, MEANS RESPONSIVE TO SAID CONTROL VOLTAGE FOR DELIVERING A SUCCESSION OF CONTROL PULSES TO SAID POWER INPUT COMPONENT FOR CONTROLLING THE ACTION OF ITS SAID GATING MEANS AND MEANS RESPONSIVE TO THE FEEDBACK SIGNALS DELIVERED BY SAID FEEDBACK COMPONENT FOR VARIABLY TIMING THE CONDUCTION INTERVALS OF SAID CONTROL PULSES SO AS TO CORRESPONDING INTERVALS OF SAID CONTROL PULSES SO AS TO CORRESPONDINGLY TIME THE GATING ACTION IN SAID POWER INPUT COMPONENT IN A MANNER TO VARY THE POWER MAGPOWER INPUT COMPONENT TO SAID INVERTER COMPONENT, WHEREBY TO VARY THE POWER MAGNITUDE OF THE OUTPUT OF SAID INVERTER COMPONENT; SAID INVERTER COMPONENT COMPRISING A TRANSFORMER INCLUDING PRIMARY AND SECONDARY WINDINGS, A PRIMARY CAPACITOR CONNECTED ACROSS THE TERMINALS OF SAID PRIMARY WINDING, AND A SECONDARY CAPACITOR CONNECTED ACROSS THE TERMINALS OF SAID SECONDARY WINDING, SAID TRANSFORMER HAVING A LEAKAGE INDUCTANCE BETWEEN SAID WINDINGS SUCH AS TO CONSTITUTE, WITH SAID CAPACITORS, AN EQUIVALENT PITYPE FILTER EMBODIED INTEGRALLY WITHIN SAID TRANSFORMER AND CAPACITORS, SUCH AS TO PROVIDE HIGHLY EFFICIENT SQUARE WAVE TO SINE WAVE CONVERSION COMBINED WITH MINIMAL WEIGHT IN SAID INVERTER COMPONENT.
