The effect of ESR on DCDC power converterStanley Chen Introduction The capacitors, inductors, and resistors in circuit analysis have ideal properties. Capacitors and inductors follow precise derivative relationships. In the real world, components do not follow such simple models. The non-ideal behavior of energy storage components is very important in the context of power electronics. This article is to discuss the effect of capacitor’s ESR (Equivalent series Resistor) characteristics on DC/DC power converter. And now, capacitors shall be presenting first. Capacitors- Principles and Equivalent Circuits Figure 1. The basic parallel-plate capacitor geometry[1] Capacitor devices come in many forms, but nearly all of them are composed of conducting plates or films, also separated by an insulating layer such as air or paper.
