Seeing in Fig. 1 circuit, S1～S4 is that master power switch pipe IGBT, D1～D4 are respectively
The endophyte fast recovery diode of S1～S4, C1～C4 be the external capacitor of power tube (also
Include the internal distribution capacity of power tube), Lr is resonant inductance, and it includes the leakage of transformator
Sense.C is partiting dc capacitor, and Tr is high frequency transformer, DR1～DR4 is output commutation diode,
L3 be output inductor, Cf be output filter capacitor.
Wherein, S1, S3 turn in turn at upper lower half, and S4, S2 are also so, S1, S4
Do not simultaneously turn on, if S1 first turns on, turn on after S4, then both conducting difference α electric angles, its
In, S1, S3 turn on prior to S4, S2 respectively, therefore the brachium pontis of S1, S3 composition is called advanced
Brachium pontis, the brachium pontis of S2, S4 composition is lagging leg.The angle of flow of two brachium pontis differs one
Phase place, i.e. phase shifting angle α, adjust output voltage size by the size adjusting phase shifting angle.
Main feature of the present invention:
1, low cost, the electric current quota of switching tube or voltage quota are low, and cost ratio is relatively low.
2, high efficiency, no-voltage conducting, the soft switch technique of zero-current switching can make efficiency reach
To 85%～88%.
3, highly reliable, by reducing running current, reduce the measures such as junction temperature to reduce device
Stress so that the reliability of product is greatly improved.
