摘要： Optimal operating techniques are disclosed for using coreless printed-circuit-board (PCB) transformers under (1) minimum input power conditions and (2) maximum energy efficiency conditions. The coreless PCB transformers should be operated at or near the ‘maximum impedance frequency’ (MIF) in order to reduce input power requirement. For maximum energy efficiency, the transformers should be at or near the “maximum efficiency frequency” (MEF) which is below the MIF. The operating principle has been confirmed by measurement and simulation. The proposed operating techniques can be applied to coreless PCB transformers in many circuits that have to meet stringent height requirements, for example to isolate the gates of power MOSFET and IGBT devices from the input power supply.

摘要： A fluxgate excitation circuit comprises an excitation inductor having a resistance Rsat and an inductance Lsat. Vin is provided by a half bridge converter of MOSFET switches (S1, S2). The excitation inductor is driven so that it enters saturation at the transition as the excitation cycle passes from positive to negative. Thus, a high input rms current value of the excitation circuit can be achieved. Because the excitation inductor is saturated for part of the cycle it may be much smaller than heretofore and have a smaller power supply. Thus, the circuit finds application in small devices.
