Advantages of Push-pull Switching Power Supply
1. Push-pull switching power supply has a high transient response speed for output current and good voltage output characteristics. push-pull switching power supply is the highest voltage utilization switching power supply among ong all switching power supply.
Due to the alternating operation of the two control switches in the push-pull switching power supply, its output voltage waveform is very symmetrical, and the switching power supply annab power output to the load throughout the whole the whole cycle. Seega, its output current transient response speed is very high, and the voltage output characteristics are good. push-pull switching power supply is the highest voltage utilization lülitamine toide toide hulgas kõik lülitamine toide tarvikud. see saab veel säilitada a suur väljund võimsus ühtlane millal sisend pinge on väga madal, so push-pull lülitamine võimsus toide on laialdaselt kasutatav in madal sisend pinge DC/AC inverterid ja aktiivne DC/DC muundur vooluringid.
2. Push-pull switching power supply is a switching power supply with excellent output voltage characteristics.
After bridge rectification or full wave rectification, the output voltage ripple coefficient and current ripple coefficient of push-pull switching power supply are very small. Therefore, a small value of energy storage filter capacitor or energy storage filter inductance is required to obtain an output voltage with very small voltage and current ripple. Therefore, push-pull switching power supply is a switching power supply with excellent output voltage characteristics.
3. The leakage inductance and copper resistance loss of push-pull switching power supply transformers are much smaller than those of unipolar magnetizing pole transformers, and the working efficiency of switching power supply is high.
The trafo of a push-pull switching power supply belongs to a bipolar magnetizing pole, and the magnetic induktsioon voltage range is more than twice that a unipolar magnetizing pole. Moreover, the transformer core does not an air gap. Seega, the magnetic permeability of the push-pull switching power supply trafo core is many times higher than that of the the transformer core of a unipolar magnetizing pole forward or tagasikäik lülitamine toide toide. See viis, the primaarne The number of pöörded of the sekundaar mähis võib olla rohkem kui kaks korda see the primaarne ja sekundaar mähised of a unipolar magnetiseeriv pole trafo. Seega, leke induktiivsus ja vask takistus kadu of push-pull switching power supply trafod on palju väiksem kui need unipolaarne magnetiseeritud pole trafod, so töö efektiivsus of switching power supply is higher.
4. sõitmine vooluring of tõuketõmme lülitamine toide toide toide is lihtne.
kaks lülitamine seadmed of the push-pull switching power supply have a common maandus klemm, mis teeb sõit vooluring palju lihtsam võrrelduna pool sild või täis sild lülitamine toide tarvikud.
5. Push-pull switching power supply do not have the possible of two control switches being connected in series at the same time as half bridge and full bridge switching power supply.
