Abstract: “Based on the theory of electromagnetic induction, a new method for obtaining alternating triangular voltage waveform across a secondary winding in a newly designed transformer change in position of core based on mutual induction is proposed when a d.c supply applied across a primary side of a transformer. This paper discusses the calculation of the flux position and the realization of the alternating triangular voltage waveform. The reasonability and validity are verified by the mathematical modulation for a ferromagnetic material is used .This method offers a new thinking for designing and modeling of transformer which is able to provide a secondary voltage.”
