Abstract

This paper describes a microcontroller modulation at 0.1 Hz for very low frequency (VLF) high voltage generator. This is used for testing field aged cable. This paper shows a simple type of the modulation circuit for VLF high voltage generator by microcontroller modulation with a sinusoidal signal at frequency 0.1 Hz and carrier signal at frequency 10 kHz. The unipolar pulse with modulation (PWM) technique is employed to control a single-phase inverter that produces a sinusoidal VLF high voltage of desired magnitude and frequency. This microcontroller modulation will be used to construct a sinusoidal VLF high voltage for non-destructive testing insulation of the crosslinked polyethylene (XLPE) cable. The digital signal controller (DSPIC-30F2010) is implemented to the inverter. In this paper show example to used microcontroller (DSPIC-30F2010) with VLF High Voltage Generator rate voltage output 3 kV peak. ฉ 2008 IEEE.
