Description of drawings
The structured flowchart of the phase-shift full bridge inverter that Fig. 1 is provided for the utility model one embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is done explanation furthermore.
Please refer to Fig. 1, the structured flowchart of the phase-shift full bridge inverter that is provided for its utility model one embodiment.As shown in the figure, this phase-shift full bridge inverter comprises full-bridge circuit 10 and high frequency transformer 20.Full-bridge inverter comprises that full-bridge circuit 10 is made up of the first switching tube S1, second switch pipe S2, the 3rd switching tube S3 and the 4th switching tube S4, and includes sustained diode in each switching tube.The composition mode of full-bridge circuit 10 is as follows: the first switching tube S1 and second switch pipe S2 form leading-bridge, and the 3rd switching tube S3 and the 4th switching tube S4 form lagging leg.In addition, full-bridge circuit 10 comprises that also first absorbs the capacitor C 1 and the second absorption capacitor C 2, is parallel to the two ends of the first switching tube S1 and second switch pipe S2 respectively.And an end of the elementary winding of high frequency transformer 20 is connected between the first switching tube S1 and the second switch pipe S2 by capacitance Cb, and the other end is connected between the 3rd switching tube S3 and the 4th switching tube S4 by pulsactor Ls.
Above structure adopts phase shift pulse-width modulation (PWM) full bridge inverter topological structure, has realized two zero soft switches (ZVSZCS) of power device, has reduced switching loss, has improved power-efficient.Specific as follows:
At first, for zero voltage switch (ZVS), because being parallel with first, the first switching tube S1 and second switch pipe S2 two ends absorb the capacitor C 1 and the second absorption capacitor C 2, and inside comprises sustained diode, they are when turning on and off, voltage can not suddenly change, and has so just realized zero voltage switch (ZVS).For Zero Current Switch (ZCS): pulsactor Ls is equivalent to a switch, and inductance was saturated when electric current was arranged, and was equivalent to short circuit; When not having electric current or electric current very little, bigger inductance is arranged.So, just can utilize its on-off action to stop the LC oscillating current reverse, because; reverse current is not enough so that the protection inductance is saturated, and its inductance value is very big, when lagging leg is opened; because pulsactor Ls is in undersaturated condition, electric current rises slow, realizes zero current turning-on.Simultaneously, utilize capacitance Cb accelerated circulation decay during circulation, make lagging leg realize zero-current switching.
Usually, the first switching tube S1, second switch pipe S2, the 3rd switching tube S3 and the 4th switching tube S4 are insulated gate polar form (IGBT) power tube.The IGBT power tube integrates the advantage of power field effect pipe MOSFET and power transistor GTR, have input impedance height, switching frequency height, peak current capacity greatly, shutoff, low-power consumption and be easy to characteristics such as driving certainly, for this reason, using the IGBT power tube has great importance for improving power-efficient.
As figure, in order reasonably to control the ON time of the first switching tube S1, second switch pipe S2, the 3rd switching tube S3 and the 4th switching tube S4, often be provided with microprocessing unit (MCU) 30 at this phase-shift full bridge inverter, pulse-width modulation (PWM) circuit 40 and isolated drive circuit 50: microprocessing unit 30 control pulse-width modulation circuits 40 produce pulse signal, this pulse signal offers full-bridge circuit 10 by isolated drive circuit 50, with the conducting of controlling the first switching tube S1, second switch pipe S2, the 3rd switching tube S3 and the 4th switching tube S4 with end.
As seen, the utility model adopts phase shift pulse-width modulation (PWM) full bridge inverter topological structure, by the rising moment and the decline moment (being the conducting moment and the shutoff moment of IGBT) of change pulse drive signal, realize the zero-voltage zero-current soft switch (being ZVZCS) of IGBT, reduce switching loss, improved power-efficient.
In addition,, reduced switching loss greatly, helped improving switching frequency, reduced the volume and weight of inverter because switching tube works under the zero-voltage and zero-current switch condition.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; anyly be familiar with this operator; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection range of the present utility model is as the criterion when looking claims person of defining.
