The high prices of energy are leading to renewed interest in the more efficient motors driven by Variable Frequency Drives or VFDs. Many types of motors such as brushless DC motors, switched ...
Fairchild Semiconductor’s Power Factor Correction (PFC) Smart Power Module (SPM) implements the Partial Power Factor Correction Switching Converter (PSC) circuit topology, which is ideal for 1-kW to 3 ...
AC-rectified power sources with capacitive filtering draw high-amplitude discontinuous currents, resulting in poor power factor and a power line rich in harmonics and high circulating currents. Poor ...
AC/DC power-factor correction (PFC) rectifiers are hugely benefitting from GaN FETs. They have very simple topologies; The inductor is the only magnetic part and this is usually a constant-frequency ...
