Abstract:
The semiconductor device of the present invention includes an insulating layer, a high voltage coil and a low voltage coil which are disposed in the insulating layer at an interval in the vertical direction, a low potential portion which is provided in a low voltage region disposed around a high voltage region for the high voltage coil in planar view and is connected with potential lower than the high voltage coil, and an electric field shield portion which is disposed between the high voltage coil and the low voltage region and includes an electrically floated metal member.
Abstract:
Disclosed is a signal transmission circuit device (200) including a feedback signal transmission unit (210) that feeds back a control output signal (Sout) as a feedback signal (Sf) to an input side circuit (200A). A logical comparison circuit (212) detects “mismatch” between input and output by performing logical comparison between a control input signal (Sin) and the feedback signal (Sf). When a state of “mismatch” between input and output occurs, a first pulse generating circuit (202) or a second pulse generating circuit (204) outputs a first correction signal (Sa1) or a second correction signal (Sa2) corresponding to a potential (high level or low level) of the control input signal (Sin), and corrects the control output signal (Sout) to the same potential (high level or low level) as the control input signal (Sin). With such configuration, the mismatch between input and output can be automatically corrected.
Abstract:
A signal transmission circuit 200 transmits input signals IN1 and IN2 each having a different transmission speed in a mutually electrically insulated manner. Signal transmission circuit 200 includes a pulse generation unit 210, transmission units 230 and 235, a latch circuit 250, and an oscillation determination circuit 270.Transmission units 230 and 235 transmit pulse signals PLS_A and PLS_B generated by pulse generation unit 210 in accordance with logical states of input signals IN1 and IN2 to latch circuit 250 and oscillation determination circuit 270 in a mutually electrically insulated manner. Latch circuit 250 restores input signal IN1 in accordance with rising edges of pulse signals PLS_A and PLS_B. Oscillation determination circuit 270 restores input signal IN2 based on oscillation states of pulse signals PLS_A and PLS_B. With such a configuration, a plurality of signals each having a different transmission speed can be transmitted in a mutually electrically insulated manner.

Abstract:
A signal-transferring device having a first circuit and a second circuit that operate on different ground references, and a third circuit for transferring signals while providing insulation between the first circuit and the second circuit. The second circuit switches a logic level of an output signal in accordance with the logic level of an input signal notified by the first circuit, and notifies the first circuit about the logic level of the output signal. The first circuit notifies the second circuit about the logic level of the input signal not only when the logic level of the input signal has been switched, but also when the logic level of the output signal notified by the second circuit does not match the logic level of the input signal.
