摘要： A signal transmission system for communicating across galvanic isolation includes a magnetic coupling having a transmitter-side inductor and a receiver-side inductor. The transmitter is coupled to the transmitter-side inductor, is referenced to a first potential, and includes a pulse generator coupled to output to the transmitter-side inductor a first state representation that represents a first logic state with multiple transitions, and a second state representation that represents a second logic state with multiple transitions. The pulse generator in outputting the first state representation is coupled to output a first information portion that includes the multiple transitions of the first state representation, and a first initial delay portion having a duration longer than a duration of the multiple transitions of the second state representation.

摘要： A method of turning on a power semiconductor switch includes receiving a first signal that characterizes a switch-on behavior of the power semiconductor switch, and detecting two or more phases of the switch-on behavior of the power semiconductor switch in response to the first signal. The method further includes detecting a peak indicative of a phase transition between the two or more phases, generating a phase signal indicative of the two or more phases, and providing a variable current to a control input of the power semiconductor switch in response to the first signal.

摘要： Circuitry for soft shutdown of a power switch and a power converters that includes circuitry for soft shutdown are described. In one aspect, circuitry for soft shutdown of a power switch includes a sense input to be coupled to a power switch receive a signal representative of current passing through the power switch, a comparator to compare the signal with an overcurrent threshold indicative of an overcurrent condition of the power switch and to output a triggering signal in response to the comparison indicating the overcurrent condition, and a gating transistor to be coupled to a control terminal of the power switch, the gating transistor configured to divert a portion of a drive signal away from the control terminal of the power switch in response to the triggering signal.

摘要： A signal transmission system for communicating across galvanic isolation. The signal transmission system includes first circuitry referenced to a first potential, the first circuitry comprising signal transmission circuitry, second circuitry referenced to a second potential and galvanically isolated from the first circuitry, the second circuitry comprising signal reception circuitry, and a magnetic coupling between the first circuitry to the second circuitry across the galvanic isolation, the magnetic coupling comprising a transmitter-side inductor and a receiver-side inductor.

摘要： An analog receiver frontend includes a first amplification circuit coupled to receive an input signal. The first amplification stage is coupled to amplify a difference between the input signal and a threshold to generate the first signal. A second amplification circuit is coupled to receive the first signal from the first amplification circuit. The second amplification circuit is coupled to amplify the first signal to generate a second signal. An output circuit is coupled to receive the second signal from the second amplification circuit. The output circuit is coupled to output a recovered signal. The recovered signal is a pulse waveform of high and low sections. An input hysteresis circuit is coupled to the output circuit to receive the recovered signal and generate a hysteresis signal. One or both of the input signal and the threshold are level shifted by the hysteresis signal in response to the recovered signal.

摘要： A control circuit for turning on a power semiconductor switch includes an input that receives a signal characterizing a switch-on behavior of the power semiconductor switch. A phase detection circuit detects two or more phases of the switch-on behavior of the power semiconductor switch in response to the signal that characterizes the switch-on behavior of the power semiconductor switch. The phase detection circuit is coupled to generate a phase signal that indicates which of the two or more phases the power semiconductor switch is currently running through. A variable current source is coupled to supply a current with a variable level to a control input of the power semiconductor switch to switch on the power semiconductor switch. The control circuit is coupled to control the variable current source in a closed control loop in response to the signal that characterizes the switch-on behavior of the power semiconductor switch.
