Abstract
Reverse recovery avoidance when converting power is provided. A first switch and second switch may be operated to supply an AC load with positive current, respective to the AC load, from a DC power source. A third and fourth switch may be operated to supply the AC load with negative current, respective to the AC load, from the DC power source. Four diodes may be employed with the switches. One diode may conduct the positive current when the first switch is off and the second switch is on. Another diode may conduct the negative current when the third switch is off and the fourth switch is on.
