摘要： Ceramic inductors are made from stacked sheets of co-fired ceramic. At least one of the ceramic sheets has a slot with a conductor disposed in the slot. The conductor has a thickness equal to a thickness of the ceramic sheet containing the slot. The conductor has a large thickness (compared to prior art co-fired ceramic inductors) and therefore can carry large currents. The present ceramic inductor can be used in power electronics applications due to the ability to carry large currents. The present ceramic inductor preferably has an inductance that decreases with increasing current. A decreasing inductance characteristic tends to increase energy efficiency in a voltage regulator when the inductor is used as an output inductor. Specifically, the variable inductance tends to substantially increase energy efficiency at low current loads without adversely affecting efficiency at high loads.
摘要翻译：陶瓷电感器由叠层的共烧陶瓷片制成。陶瓷片中的至少一个具有设置在槽中的导体的槽。导体的厚度等于包含槽的陶瓷片的厚度。导体具有较大的厚度（与现有技术的共烧陶瓷电感器相比），因此可以承载大电流。由于能够承载大电流，本陶瓷电感器可用于电力电子应用中。本陶瓷电感器优选具有随着电流增加而减小的电感。当电感器用作输出电感器时，降低的电感特性趋向于提高电压调节器中的能量效率。具体来说，可变电感倾向于在低电流负载下显着提高能量效率，而不会在高负载下不利地影响效率。

摘要： An energy transfer element having an energy transfer element input winding and an energy transfer element output winding. In one aspect, the energy transfer element input winding is capacitively coupled to the energy transfer element output winding. The energy transfer element is capacitively coupled to electrical earth. One or more additional windings are introduced as part of the energy transfer element. The one or more additional windings substantially reduce capacitive displacement current between the energy transfer element input winding and energy transfer element output winding by balancing the relative electrostatic fields generated between these windings and/or between the energy transfer element and electrical earth by canceling the electrostatic fields generated by all windings within the energy transfer element relative to electrical earth through the selection of the physical position and number of turns in the additional windings.
