Ensuring Electromagnetic Compatibility of Microprocessor Devices with Toroidal Chokes

Research is focused on the problem of electromagnetic compatibility of toroidal chokes with microprocessor elements of printed circuit boards. Evaluation of the influence of interference induced by chokes is carried out using the developed mathematical model and numerical methods for calculating the electromagnetic field. The choice of the mutual arrangement of the chokes on the microprocessor integrated circuit is carried out as a result of solving the optimization problem by the gradient method, taking into account the given restrictions on the conditions for ensuring electromagnetic compatibility.
