An L d i /d t effect model in the float ground driver system of plasma display panel (PDP) is established. First, considering key parasitic parameters, this study analyses the L d i /d t effect appeared in power supply and ground pins because of switching transition of float‐ground integrated circuits. Second, a set of differential equations model is described and validated with a good agreement with experiments. Based on the model, time‐domain transient voltages and frequency spectra of the L d i /d t effect are simulated and analysed with different values of parameter elements. Finally, subject to system demand limitation and the proposed model, the manual parameter design for reducing the L d i /d t effect is presented, and a PDP system is used to validate the proposed approach.
