Abstract :
An interleaved low-voltage half-bridge converter is proposed in this paper. With a master-slave peak current control, charge balances of the main transformers are automatically achieved. Thus current runaway is avoided without an additional correction circuit. It is shown that the steady state analysis and simulation results are in good agreement. A 48 V input, 1.5 V/60 A output prototype is built to verify the proposed control method
