Half Bridge Inverter and Single-phase Full Bridge

Half Bridge Inverter

  

It is  known as the “inverter leg”.

->Basic building block for full bridge, three phase and higher order inverters.G is the centre point.

Both capacitors have the  same value. Thus the DC link is equally “spilt” into two.

The top and bottom switch has to be “complementary”, i.e. If the top switch is closed (on), the bottom must be off, and vice-versa.

 Single Phase  Full  Bridge

 

•Full bridge (single phase) is built from two half-bridge leg.

 

•The switching in the second leg is delayed by 180 degrees” from the first leg.
