  • Patent number: 10811985
    Abstract: A system including a converter is disclosed. The converter includes a first switch having one or more first controllable switches coupled in parallel across at least one diode. A first controlling unit is operatively coupled to the converter. The first controlling unit is configured to determine a temperature of the one or more first controllable switches. The first controlling unit is further configured to compare the determined temperature of the one or more first controllable switches with a transition temperature at which a first power loss of the one or more first controllable switches is equal to a second power loss of the at least one diode and control a switching state of the one or more first controllable switches based on the comparison of the determined temperature with the transition temperature.
