摘要
Recent technological developments in the field of battery technology and fast charging favors electric transportation ecosystem. However, higher charging rates threaten reduced battery life cycles. Hence, level I charging systems for household application are extensively researched. Traditional LLC resonant converter is most attractive topology for on-board electric vehicle charging. Moreover, compounded charging characteristics of Li-ion battery demands broad output voltage and switching frequency variation. This, in turn, necessitates burst mode strategy for LLC converter during pre-charging recovery phase of a drained battery. Notwithstanding, burst mode strategy has many detrimental effects on the charging system and must be avoided. Therefore, this article proposes series-parallel LCLC resonant converter for electric vehicle charging. The presented converter provides a broad output voltage range and thus alleviates need for burst mode strategy when operated with synchronous pulse frequency modulation (PFM) and pulse width modulation (PWM). Experimentation results of 3 kW prototype confirm feasibility for intended electric vehicle charging application.
