Abstract: In this paper, a proposed inductive voltage divider is described to be operated manually and automatically, which is not provided by the ordinary decade inductive voltage dividers. Design of that programmable inductive voltage divider (PIVD) is investigated and presented in detail. The introduced PIVD mainly consists of inductive elements, relays, microcontroller to get the required output voltage ratios through its three stages. This PIVD is designed to produce 999 steps in the range from 1×10-3 to 999×10-3 output ratios using minimum inductive elements and reed relays. Simulation of this PIVD has been performed and illustrated as well as practical design components are discussed in detail.
