Power supply control loop response measurements = Bode plot (AppCard)

To ensure the stability of voltage regulators and switched mode power supplies, the control loop behavior must be measured and characterized.
A well compensating voltage controller enables stable output voltages and reduces the influence of load changes and supply voltage variations. The quality of this control circuit determines the stability and dynamic response of the entire DC/DC converter.

Tips and tricks on Double Pulse testing (AppNote)

Power semiconductors (IGBT or MOSFET) are controlled devices, which are used to realize these converters. Even though the semiconductor industry has made a significant progress in the development of powerful and efficient components, power losses still occur in these components and cause them to heat up. In order to design an effective cooling system, it is necessary to know the power losses occurring during the operation of a circuit as precisely as possible.
