Deformation of the half bridge converter principle of electric circuit diagram
For high input, high power output, generally USES the way of circuit as shown. In the circuit, switching devices V1, V2, V3 and V4 as a group, both in series and can reduce the single pipe pressure values. In the practical application circuit switch device in the V1, V2, V3 and V4 can adopt double pipe or in parallel, can solve the problem of large current output. Common transformer can improve the utilization efficiency of transformer, and has the ability to resist imbalance. In series of half bridge circuit, power transformation V1, V2 and V3, V4 each maximum withstand voltage value of the switch tube is only ucs 1 or Uc2 value, if C1 = C2, the ucs 1 = Uc2 = Uin / 2 value, therefore can choose to reduce the pressure switch tube. Another V1, V2, V3 and V4 manifold can be used in parallel work, increasing the capacity of the output current; T can work on the positive and negative direction for transformer, greatly improve the efficiency of the transformer. In view of the above advantages, the circuit has been more widely used, especially in the occasion of high input voltage and high power output, its application is becoming more common.
