1. conversion that is controlled between first and second voltage sources is comprised by the saturated method of transformer of the transformer of one of described voltage source power supply the output voltage disturbance is reduced to minimum and prevents:

  • Turn-off first switch that is connected with this first voltage source;

    The second switch that temporary pulse-on is connected with this second voltage source;

    WithCalculate change-over time by the compensation weber area that calculates second voltage source, saturated to prevent transformer;

    Permanently connect this second switch in this change-over time.
