  • Abstract
    A new approach for flux imbalance prevention is proposed in this paper. The basic idea is to suppress DC component of the transformer primary voltage using the closed control loop around the hybrid amplifier with the first order low-pass filter and the integrator in the feedback path. The operation of proposed scheme is analyzed in detail analytically and by means of computer simulations. Experimental results are in accordance with simulations and confirm the suitability of the cost effective solution.
