ISEL. 2017, pp. 1-14http://hdl.handle.net/10400.21/8676The paper presents the design stages of a single-phase Silicon Carbide bidirectional DC-AC converter. This includes the LCL filter design responsible to meet grid connection requirements. A 3kW laboratory prototype of the power converter is built employing a low-cost phase locked loop and its results are presented. The design of the low-cost phase locked loop and its implementation are depicted in some detail.engSiC bidirectional AC-DC converterInverterVariable frequencyPLLLCL filterDesign of single phase SiC bidirectional DC-AC converter with low-cost PLL for power factor correctionpreprint10.20944/preprints201704.0184.v1
