Abstract
A method of operating an electric vehicle charging apparatus for a vehicle to grid interface comprising a first full bridge converter configured to convert a grid supply to a DC link and a primary full bridge converter connected to the DC link and configured to provide an output alternating current for use in vehicle charging. The method includes detecting a charging power requirement for a vehicle; determining a required voltage for the DC link to enable the converter to supply power for satisfying the charging power requirement when operating at full duty cycle; operating the primary full bridge converter at full duty cycle; controlling the voltage of the DC link to the required voltage.
