Abstract

PURPOSE: To ensure a long-distance wiring as well as a high-speed and highprecision input by giving an amplitude limitation to the voltage level to the secondary side capacitor via the primary side winding voltage when the pulse voltage is induced to secure an equivalent read-out for the state signal of the secondary side.
