The present invention is directed to an electric vehicle charger that may include power electronics, one or more controllers, and one or more cable/connector plugs. The disclosed bi-charger may operate bi-directionally. Power components may be arranged in a charger enclosure in a configuration providing the optimum air flow over a heat sink(s) that will allow the most heat to be moved out of the charger enclosure with the least effort. The disclosed charger may use a combination of forced and natural convection to effectively cool the system. Power stages may be mounted in the enclosure and a control tray may be mounted above the power stages. The disclosed charger may use a three-power stage architecture. The disclosed charger also uses a configuration and method of mounting and positioning the power components within the enclosure that results in a smaller and more power dense piece of equipment.
