With the increasing spread of high-voltage power semiconductor components build with silicon carbide (SiC) technology, which operate at switching frequencies above 100 kHz, the requirements for their gate control are becoming more and more demanding. Besides the bipolar, positive and negative driving voltages fo

As soon as a power supply designer needs to comply with military standards, he might need to take into account the transparency or holdup requirement. Transparency requirement is the minimum amount of time during which input power can go away but the equipment is expected to remain operational. This power int
