Evaluation of results shows that highest efficiency has been achieved during utilization of the MBR20200CT. SiC diode is in comparisson with other types the worsest solution for such applications. The best performance of MBR20200CT is caused due to the lowest value of forward voltage VF, which in connection with high peak value of diode current and due to its sinusoidal waveform reduces condution losses of diode. Lower efficiency in the case of LQA12T300C and SDT10S30 is caused almost due to higher value of VF and thus due to higher condution losses
