Figure 1: Power stage of the flyback converter (simplified)

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power

SiC MOSFET Efficiency and Protection without Compromise

Click image to enlarge

Figure 1. Comparing SiC with conventional Silicon MOSFETs reveals the clearly superior semiconductor characteristics of the SiC material, which allows the construction of significantly smaller switching devices

The lower sheet resistance of wide-bandgap SiC materials (typically 1/100th that of conventional silicon) results in smaller devices for a given current capacity – valuable in space saving applications. In addition, the electric-breakdown- field for SiC (approximately 2.8 MV/cm) allows for a much shorter isolati
