Abstract

The principle of full-bridge DC-DC converter is briefly expounded, including the two typical control methods, named limited dual polarity hard-switch control and phase-shifted soft-switch control. Then the common mode noise equivalent circuits of full-bridge DC-DC converter are deduced, taking the common mode noise of the bridge leg´s midpoint into account, and the difference between the two typical control strategies is illustrated through theoretical analysis. In the end, simulations are performed to validate the circuit models and theoretical analysis.
