Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...
OBJECTIVES This study examines the potential use of interviewer-rated health (IRH) as a complementary measure of self-rated health (SRH) through a systematic comparison of their components and mortality-predictive powers in the Chinese elderly population. METHODS This study used a nationwide dataset with more than 12,000 adults aged 65 or older drawn from the 2005 and 2008 waves of the Chines...
