DELTA vs WYE: Three Phase EMI Filters
Industrial applications predominantly require a high power supply to support high-power equipment (such as induction circuits, inverters, and heating systems). Therefore, high power equipment is generally designed for 3-phase (or poly-phase) AC power. The 3-phase AC power plays a crucial role in the electrical system design as it splits the total power into various phases, and thus optimizes the power system (both generation and distribution) and equipment design. 3-Phase System It consists of three current-carrying conductors (or phases). All three phases (A, B, and C) are set at the same voltage and frequency and phase-shifted from each other by an angle of 120°. It helps to transfer constant power during the electrical cycle. There are two configurations of 3-phase systems, namely Delta and WYE configurations which maintain equal loads. 3-Phase EMI Filter High power conversion (such as rectifying) generates higher-order harmonics of different switching frequ...
