It is common for Internet of Things (IoT) devices, industrial sensors, meters, precision, and medical equipment to require both a positive and negative voltage. Often, these voltages must be ...
In order to correctly turn on and off some switches, such as SiC transistors, it is usually required to drive its gate between a positive and a negative supply voltage (+20V and -5V for SiC MOSFETs, ...
Negative input impedance in power supplies can amplify external line noise, causing deceptive conducted emissions failures.
