Calculation and modelling of transformer parasitic capacitance

WebTypically, for isolated dc-to-dc power supply applications with high output current, the use of synchronous rectifiers (particularly MOSFETs) is dominant. A high output current also introduces a high di/dt on the rectifiers. For high efficiency, the choice of MOSFET is mainly determined by the on resistance and the gate charge. However, little attention is given to … WebParasitic capacitance effects circuits, in this case our HBM circuit by either limiting the amount of energy that can be forced onto a pin or by adding to the energy, as the parasitic elements store charge then release it at the time of the intended event, causing a higher energy waveform than expected. WebAdding parasitic capacitance in parallel with the low resistor values (Rg) will produce undesirable results. When capacitance is in parallel to the Rf (feedback resistor), then one questions why the full bandwidth was not obtained.
