... different devices were designed, fabricated and tested: a compact DC/DC converter, a galvanic separator for serial digital bus and a transformer for high-voltage generator. Findings Breakdown field intensity higher than 40 kV/mm was obtained for the test samples set, whereas the best breakdown field...

...Y. Srinivasa Rao Purpose The purpose of this paper is to study the variation of the temperature coefficient of resistance (TCR) of polymer thick film resistors, namely, PVC‐graphite thick film resistors, with parameters such as volume fraction, grain size, and high voltage. Design/methodology...

... of PVC:per cent weight of graphite) to 10 per cent:90 per cent. © MCB UP Limited 2003 Noise High voltage Resistors The study of current noise in thick film resistors has been an important subject to hybrid microcircuits because of increasing usage of thick film resistors in low...

...Y. Srinivasa Rao; M. Satyam The effect of high voltage pulses on the resistance of polymer thick film resistors (PTFR) is studied. It is found that the resistance decreases with both the amplitude and duration of the high voltage pulses and with the number of pulses. The change in resistance...

...Y. Srinivasa Rao; M. Satyam The effects of material parameters and processing conditions on the resistance drop by high voltage discharge in PVC – graphite thick film resistors are studied in this paper. The resistance drop increased upon an increase in graphite aggregate size, which is a function...
