Sažetak
A DC-DC converter made of two identical IGBT full bridge power circuits is built. The two circuits are directly connected in parallel and driven with only one control circuit originally built for one IGBT bridge. One signal drives two corresponding IGBTs in parallel bridges without any additional circuits for current sharing. The main causes of possible current unbalance were identified by simulation. The difference among transformer leakage inductances has, by far, the most significant influence on current sharing between two circuits. This was confirmed by measurements. It is concluded that transformer tolerances regarding leakage inductances that can be achieved in normal series production will ensure an acceptable current sharing.
