This paper presents the results and gained experience trom the student design project task in power electronics, based on boost converter test board. In the project task the students are asked to calculate the main boost converter circuit parameters capacitor C and inductor L, addltlonally they are also required to design the inductor L in order to meet the project goals. The whole project design...
This paper presents a safe start-up procedures of an isolated bi-directional DC-DC converter in buck and boost modes. This converter has been developed as a part of multifunctional up to 4 kW power supply system that uses a high voltage (450 V) DC-link. The isolated bi-directional DC-DC converter can charge 28 V batteries and supply auxiliary low voltage DC loads. Additionally, the isolated bidirectional...
Introduction: It has long been known that immune complexes consisting of antigen and IgG antibodies are potent inhibitors of humoral immune responses. The inhibitory effect on antibody production has been shown to depend on co-ligation of the B-cell antigen receptor (BCR) and the low affinity receptor for IgG (FcγRIIb, CD32). This study was initiated to examine the effect of CD32 ligation on IgE...
