Abstract

Modern power electronic switches such as SCR's, Power MOSFET's and IGBT's require electrical isolation for the gate drive. The cost of providing isolation by conventional wire wound transformers has become prohibitive. Planar magnetics based on thick film technology and printed circuit boards (PCB's) provide an ideal solution to cost while improving the manufacturing process. A complete electrical model of the pulse transformer is presented and the main parameters such as rise time, droop and fall time are compared to a conventional device. High frequency losses are found from Finite Element Analysis (FEA) and these are compared with measurements up to 1 MHz. Experimental results are presented showing the operation of the new device in a typical switching circuit.
