摘要： A transformer having galvanically isolated windings defines a primary side and a secondary side of a power conversion apparatus. A switch couples power from a source on the primary side via the transformer to a load on the secondary side. A first circuit assembly has primary-side circuitry galvanically coupled to a port for connection to an input power source. The primary-side circuitry includes a primary-side communicator for sending or receiving control information used in controlling operation of the power conversion apparatus. A second circuit assembly has secondary-side circuitry galvanically coupled to a port for connection to a load. The secondary-side circuitry includes a secondary-side communicator for sending or receiving the control information. The first and second circuit assemblies are mechanically separable as assemblies from one another, are galvanically isolated from one another, and are configured to be placed in positions relative to one another to enable the primary-side and secondary-side communicators to cooperate to pass the control information.

摘要： A closed-loop feedback system has first and second gain elements. The first gain element has a transfer function such that Xd=Kg * (Xcont).sup.z, where Xcont is a control variable input signal of the first gain element, Xd is a controlled variable output signal of the first gain element, and Kg and z are independent of Xcont. The second gain element has a transfer function h1 such that Xcont=h1(Xe) where Xe is a control variable input signal of the second gain element and Xcont is a controlled variable output signal of the second gain element. The function h1 is of a form which satisfies [1/h1(Xe)]*[.delta.h1(Xe)/.delta.Xe]=Ke, where Ke is independent of Xe.

摘要： A threshold receiver circuit consists of a reference subcircuit and one or more signal input subcircuits. The reference subcircuit derives a mirror voltage by regulating a reference current flowing through an external reference resistor. The mirror voltage is distributed to each of the signal input subcircuits. Within each signal input subcircuit a signal transistor has its gate connected to the mirror voltage and its drain connected to a common input node, thereby causing a signal current to flow into the common input node which is proportional to the reference current. The signal current also flows through an external signal input resistor which is connected to the input node, and into the external input signal source. The input node voltage is thus equal to the input signal source voltage plus the voltage-drop across the signal input resistor. This input node voltage is compared to an internal reference voltage by a comparator which is also connected to the common input node. Thus, a logic output signal is produced by the comparator corresponding to the magnitude of the input signal source. Hysteresis is added at the comparator reference input, and also by means of one or more hysteresis transistors whose drains are connected to the common input node. The gates of the hysteresis transistors are controlled so that when the output logic state is low, they are connected to the mirror voltage and a hysteresis current is produced, and when the output logic state is high, no hysteresis current is produced.
