Title:
SIGNAL TRANSMISSION CIRCUIT AND POWER CONVERSION DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2015/136769
Kind Code:
A1
Abstract:
In a signal transmission circuit (1000) for transmitting a signal via an insulating transformer (10), a first circuit (100) connected to a primary coil (11) of the insulating transformer (10) transmits a plurality of continuously generated pulses alternately to first and second ends of the primary coil (11) per change of the logical value of an input signal (IN). A second circuit (200) connected to a secondary coil (12) comprises: a comparator (220) having two input terminals connected to first and second ends of the secondary coil (12); an SR latch circuit (270) for outputting an output signal (OUT); and a signal generation circuit (210) for generating a set signal and a reset signal, which are input to the SR latch circuit (270), by partially masking respective reference set and reset signals based on the output signal of the comparator (220).
