Various examples related to electromagnetic interference (EMI) energy mitigation techniques are provided. In one example, a method includes adjusting switching angles of a switching circuit based on resolution bandwidths (RBWs) associated with an EMI frequency spectrum of the switching circuit and weight coefficients of the RBWs. The total energy of the switching circuit can be reduced by adjusting an average duty cycle of the switching circuit. EMI spectrum information can be determined based upon switching angles of a switching circuit. For example, weighted errors corresponding to differences between reference harmonic magnitudes and determined harmonic magnitudes can be determined. In response to a comparison of a maximum weighted error to a preset tolerance threshold, adjustment to the switching angles can be determined and/or applied.
