One major source of controversy related to possible health effects radiofrequency radiation (RFR) is the large number reported statistically significant exposure, over entire RF part spectrum and a wide range exposure levels, even as agencies do not find clear evidence for hazards at levels within current IEEE ICNIRP limits. This Perspective considers 31 studies genetic damage produced by RFR f...

Hysteresis current control method is vastly used in PWM inverters because of simplicity in performance, fast control response and good ability in limiting peak current. However, switching frequency in hysteresis current control method with fixed bandwidth has large variation during a cycle and therefore causes non-optimal current ripple generation in output current. One of basic problems in imp...
