In this article, the design of a photometer circuit based on current-to-frequency converter is presented. This piecewise linear that makes most feedback to ensure relationship between input photocurrent and output frequency. Here, Proteus simulations were used verify performance proposed circuit, electronic experimental results shown be in total agreement. The showed rejected better additive wh...

Soft Switcing techniques have recently been applied in the design of dc-ac converters, in order to achive better performance, higher efficiency, and power density. One of the soft switching techniques uesd in inverters is resonant dc links. These topologies have some disadvantages such as irregular current peaks, large voltage peaks, uncotrollble pulse width, etc. Another soft switching method ...
