Single-Phase Half-Bridge Voltage Source Inverter The single-phase voltage source half-bridge inverters, are meant for lower voltage applications and are commonly used in power supplies. Low-order current harmonics get injected back to the source voltage by the operation of the inverter. This means that two large capacitors are needed for filtering purposes in this design.

Back inNeil Postman described television and school as two competing learning systems, and he estimated that television was fast becoming "the first curriculum. At that time, many of us in social studies education considered television to be a promising news and entertainment source and discussed its professional potential for replacing 16mm films and their troublesome projectors in our schools.
I recall that we enjoyed the easy accessibility of entertainment and news but were not watching TV as a daily thing. In my family, for example, we often watched the evening news, and now and then selected special dramatic, historical, or variety programs for family viewing.
Before the s, few social studies educators contemplated the growing power of television to socialize and teach see Hepburn At that time, in social science courses, social studies educators learned about the process of the "political socialization" of youth, and many teachers taught their students about those influences on their lives.
Today educators would be more likely to refer to the process as the shaping of civic attitudes and behavior, or "civic socialization.
Those several agents were not considered of equal importance in the civic development of young people. The family was considered the predominant influence, exerting particularly strong sway on political identification and partisanship e.
The school's influence was considered minimal, based mainly on a study by Langton and Jennings of high school students. Their five-itemquestionnaire was soon challenged by educational researchers for its lack of validity and reliability, but the study is still cited today.
ByTorney, Oppenheim, and Farnen found persistent evidence that classroom experiences do affect civic understanding, but the conventional wisdom persisted for some years that social studies curriculum and schooling have little or no effect, either negative or positive.
Church and social groups were considered significant influences on civic attitudes and behavior in that early literature. The mass media, however, were given little attention e. There was some consideration of social conditions.
For example, social differences related to race were recognized as studies examined ways that African Americans came to terms with the political situation in the United States and experienced a duality in the socialization process e.
But societal conditions were somewhat peripheral to the "agents" model. Moreover, the influencing agents were usually viewed as independent or disconnected--each exerting a separate influence on young people see figure 1.
It is time for social studies educators to revise the old perception of learning and take into account the extensive direct and indirect effects on youth of electronic media. Not only do the electronic media shape perceptions of young people, but there is plenty of evidence that the mature population, including teachers and parents, are affected as well.
Let us examine some foundational data about the ubiquity and content of television.
More than 99 percent of U.Electronic media allows information and ideas to travel almost instantly from its source to the public through the Internet.
