Claim Text:
1. A signal transmission circuit, comprising: a resonant reactor connected with a first voltage supply point, which a first voltage is supplied to; a resonant capacitor connected between a second voltage supply point, which a second voltage is supplied to, and an output terminal; a first switching element connected between the resonant reactor and the output terminal and configured to be turned on and off by a first switching signal; and a second switching element connected between the output terminal and the second voltage supply point and configured to be turned on and off by a second switching signal, wherein the first switching signal and the second switching signal are respectively control signals configured to periodically turn on and off the first switching element and the second switching element with elapse of time, the signal transmission circuit further comprising a timing adjustment circuit configured to store a previous voltage that is a voltage of a signal output from the output terminal in a last cycle, compare the previous voltage with a voltage of a signal output from the output terminal in a current cycle and adjust a timing of transition of the first switching signal and a timing of transition of the second switching signal, based on a result of comparison.
