主 题:Power electronics active gate driving electromagnetic compatibility Newton’s method
摘 要:High-frequency switching of power transistors in power electronic systems can cause electromagnetic *** approaches for reducing high-frequency disturbances,such as inserting an additional gate resistor,lead to increased power *** makes achieving both electromagnetic compatibility and power efficiency *** gate drivers help to find a trade-off between these ***,only narrow-band disturbances must be ***,a target signal with a spectrum notched at some frequencies can be *** target signal can be reached by a target-signal-oriented control of the transistor’s *** leads to steeper switching slopes,such that the power losses are less *** arbitrary target signals is *** transistor signal exhibits some physical limitations.A constraint satisfaction problem must be solved,and the gate drive signal must be optimized by applying a residual and Newton’s *** proposed optimization process in the frequency domain is based on the circuit simulation method named“harmonic balance.Measurements on a DC/DC converter exhibit the benefits of this method.
