converters for the use in photovoltaic‚ fuel cell systems are discussed in this paper from the viewpoint of power losses and efficiency. State of the art converters with switching frequency within the range of 25 kHz with IGBTs to 100 kHz with power MOSFETs and the highest efficiency close to 98%‚ depending on the load conditions‚ is considered. A comparison and discussion of the highest efficiency high power DC/DC boost converters is also presented in this paper. Key words: boost DC/DC converters‚ high

MICROCHIPS: Some important microchips technologies are listed below: 1. CMOS‚ in computer science‚ acronym for complementary metal-oxide semiconductor. A semiconductor device that consists of two metal-oxide semiconductor field effect transistors (MOSFETs)‚ one N-type and one P-type‚ integrated on a single silicon chip. Generally used for RAM and switching applications‚ these devices have very high speed and extremely low power consumption. They are‚ however‚ easily damaged by static electricity.

Battery Desulfator Errata In my battery desulfator article on page 84 of HP77‚ the value for C2 should have been 0.0022 ìF‚ not 0.022 ìF. My mistake. I have put up a Web page that will give more details to help you build and use the desulfator circuit. I will place updates there‚ and will add a guestbook soon to allow comments and questions to be posted. I encourage a group effort in this‚ since I don’t have all the answers. Thanks.
