Design considerations for an optically controlled static switch autonomous module

In this paper, a new method is suggested for designing an optically controlled power static switch module. Considerations are presented in order to reach an optimal design. Plastic optical fiber is used to transfer optical signals generated by the controller. Circuits of the module don´t use auxiliary power supply. Therefore, problems due to power supply isolation are removed and less complexity is obtained. Losses are reduced using switching techniques for regulation. The module can operate in a wide range of switching frequency and could be used in either dc or ac applications.
