Abstract
A self-oscillating sine-wave oscillator is proposed with a frequency range from 20 kHz up to 2 MHz. The voltage amplitude ranges from 10 V, up to 350 V peak. A stepwise selectable capacitor and a variable inductor are used to adapt the frequency. Also DC injection in the test object is possible. It is mainly intended for measurement of losses in ferrite cores
