METHODS AND SYSTEMS FOR OPERATING HYBRID POWER DEVICES USING MULTIPLE CURRENT-DEPENDENT SWITCHING PATTERNS

An integrated circuit includes a hybrid switch 60c having first and second switching devices of different type therein. A control circuit 120 is provided, which is configured to drive the first and second devices with respective first and second control signals having first and second unequal duty cycles, respectively, when the first and second devices are supporting a forward current in a first current range. The control circuit is further configured to drive the first and second devices with respective third and fourth control signals having third and fourth unequal duty cycles, respectively, when the first and second devices are supporting a forward current in a second current range outside the first current range. The first duty cycle may be greater than the second duty cycle and the third duty cycle may be less than the fourth duty cycle. 集成电路包括其中具有不同类型的第和第二开关器件的混合开关60c。提供了种控制电路120，其被配置成当第和第二器件正支撑在第电流范围内的正向电流时，用分别具有第和第二不相等的占空比的各自的第和第二控制信号驱动第和第二器件。所述控制电路还被配置成当第和第二器件正支撑在所述第电流范围外的第二电流范围内的正向电流时用分别具有第三和第四不相等的
