Een Residual Current Device (RCD, reststroomapparaat) detecteert reststroom (dat wil zeggen lekstroom van een elektrisch systeem naar de aarde) en koppelt een circuit automatisch los van de stroomvoorziening wanneer de reststroom een vooraf ingestelde drempelwaarde oversch...
aA large charging current causes the large voltage across the external resistance in the Li-ion battery-pack system. It makes the charger circuit detect the transition point of the CC to the CV stage more early than that with a small charging current. The voltage is added to the voltage at...

In this paper, a new theory of current filament formation in MOSFET-Mode IGBTs is presented, for the first time, based on large scale 3D & 2D TCAD simulations. It was found that current filaments appear because the total collector current increases while current filaments are growing. The tot...
The high fault current of dc line is a major threat to multiterminal voltage-source-converter-based HVDC (VSC-HVDC) system. However, dc circuit breaker (DCCB) with large capacity and fast breaking speed is still under development. Therefore, fault current limitation is vital for the multitermin...
An improved current sensing circuit is provided in, or for use with, a power delivery circuit having a current controlling device of the type which includes auxiliary current sensing terminals. The cu
An improved circuit for controlling the maximum current in a MOS power transistor, in which resistor is in series with the drain- source path of the MOS power transistor. The supply terminal of a transconductance operational amplifier is connected to the output of a voltage-raising or charge pum...

A control circuit (18) and method for regulating the current flow through a series connected inductor (20) and transistor (16). The circuit comprises an operational amplifier (34) for receiving a first voltage proportional to the current flow, for receiving a variable second voltage, and for ...
IGBT Short-Circuit Capability The short-circuit withstand time of an IGBT is related to its transconductance or gain and the thermal capacity of the IGBT die. Higher gain leads to higher short-circuit current levels within the IGBT, so clearly lower gain IGBTs will have lower sho...
