If convert dc to ac inverter, the dc voltage is low, the step-up transformer through communication, namely the standard ac voltage and frequency inverter for the large capacity, because of the dc bus voltage is higher, ac output generally don't need a step-up transformer can be up to 220 v, in the small capacity of the inverter, due to the low dc voltage, such as 12 v 24V, it is necessary to design the booster circuit in the small capacity inverter generally have a push-pull inverter circuit Full bridge inverter circuit and high frequency inverter circuit of pressure three, push-pull circuit, the step-up transformer neutral plug connected into the power, the two power tube work alternately, ac power output, because of the power transistor were juggle, drive and control circuit is simple, because the transformer leakage inductance of the has certain, can limit short circuit current, thus improving the reliability of the circuit The disadvantage is that the utilization rate of the transformer is low, and the ability to drive the inductive load is poor
