摘要: Converters with a dc port and single-phase ac must store energy to buffer the inherent double-frequency power flow at port. The minimum storage required isolate ripple from is presented, leads capacitance for converters that use capacitive storage. This paper presents manage decouple capacitor ripple. A allows designer make choice of voltage independent other system voltages. combination an link converter dramatic increase in reliability: it shown nominal ratings up 200 W can be designed expected mean-time-between-failure on order 1.4 × 106 h-sufficient hundred-year operation long-life applications such as photovoltaic LED lamps. large life achieved minimal extra cost.
