摘要： An isolated power transfer device includes a transformer formed in a multi-layer substrate of an integrated circuit package. A primary winding of the transformer is coupled to a first integrated circuit to form a DC/AC power converter and a secondary winding of the transformer is coupled to a second integrated circuit to form an AC/DC power converter. The first and second integrated circuits are electrically isolated from each other. The first integrated circuit includes a lightly doped drain MOSFET integrated with conventional CMOS devices and the second integrated circuit includes a Schottky diode integrated with conventional CMOS devices. The isolated power transfer device includes a capacitive channel for communication of information across an isolation barrier from the second integrated circuit to the first integrated circuit. Capacitors of the capacitive channel may be formed in the multi-layer substrate of the integrated circuit package.

A first portion of the direct current flows through the first resistance and a second portion of the direct current flows through the second resistance. The circuit further includes a current sensor having an opening, first and second conductors inductively coupled with the current sensor, and a switching circuit having a pair of switches structured to alternatingly switch in order that the second portion of the direct current alternatingly flows through the first and second conductors. The second portion of the direct current flowing through the first conductor passes through the opening of the current sensor in a first direction and the second portion of the direct current flowing through the second conductor passes through the opening of the current sensor in a second direction opposite to the first direction.

摘要： The invention provides a method for DC voltage measurement. First, an input DC voltage is received. A temporary disturbance signal is then added to the input DC voltage to obtain a disturbed signal, wherein an amplitude of the temporary disturbance signal is greater than precision level of an analog-to-digital converter. The disturbed signal is then converted from analog to digital with the analog-to-digital converter to obtain a plurality of samples with different values. An average value is then derived from the samples. Finally, the average value is output as a measurement value of the input DC voltage.

摘要： A conversion circuit having polarity sensing wherein an input signal is converted into two signals each of which is the inverse of the other. A pair of switches, arranged to conduct these signals selectively, are connected to an integrator which accumulates the voltage of these signals within predetermined limits set by a pair of comparators. Control logic between the comparators and the switches, together with a third comparator producing a binary signal in response to polarity changes of the input signal, cause alternate conduction of the signals and produce a square wave pulse train having a pulse rate proportional to the absolute magnitude of the input signal.
