1. a kind of LC series resonances high frequency chain matrix half-bridge inverter topology, it is characterised in that:

  • The topology is gone here and there by half-bridge LCConnection resonance inverter, high frequency transformer T, matrix converter, CL mode filters are sequentially connected composition;

    Wherein, half-bridge LC series resonant inverters are by DC input voitage Ui, controlled tr tube S1, controlled tr tube S2, inductance Lr

    Electric capacity CrComposition;

    Matrix converter is by controlled tr tube SP1, controlled tr tube SP2, controlled tr tube SP3, controlled tr tube SP4, gate-controlled switchPipe SN1, controlled tr tube SN2, controlled tr tube SN3, controlled tr tube SN4Composition;

    CL mode filters are by inductance Lf, electric capacity CfWith load R compositions;

    In the topology, DC input voitage UiPositive pole and controlled tr tube S1Colelctor electrode be connected, controlled tr tube S1HairEmitter-base bandgap grading respectively with inductance LrOne end, controlled tr tube S2Colelctor electrode be connected;

    DC input voitage UiNegative pole respectively with it is controllableSwitching tube S2Emitter stage, high frequency transformer T primary sides one end be connected;

    Inductance LrThe other end and electric capacity CrOne end connection, electricityHold CrThe other end be connected with the other end of high frequency transformer T primary sides;

    One end of high frequency transformer T secondary respectively with controlled tr tube SP1Colelctor electrode, controlled tr tube SP3Colelctor electrode be connected,Controlled tr tube SP1Emitter stage and controlled tr tube SN2Emitter stage be connected, controlled tr tube SN2Colelctor electrode respectively with canControl switching tube SP2Colelctor electrode, inductance LfOne end, electric capacity CfOne end be connected, controlled tr tube SP2Emitter stage opened with controllableClose pipe SN1Emitter stage be connected;

    Controlled tr tube SP3Emitter stage and controlled tr tube SN4Emitter stage be connected, controlled tr tubeSN4Colelctor electrode respectively with controlled tr tube SP4Colelctor electrode, electric capacity CfThe other end, load R one end be connected, load R it is anotherOne end and inductance LfThe other end be connected;

    Controlled tr tube SP4Emitter stage and controlled tr tube SN3Emitter stage be connected, high frequencyThe other end of transformer T secondary respectively with controlled tr tube SN1Colelctor electrode, controlled tr tube SN3Colelctor electrode be connected.
