摘要： A system structured to transfer control information between an IFA (I/O interface adapter) and an I/O processor, and I/O data between an IFA and a CDB (channel data buffer) has separate interfaces for these transfers. The control interface includes a multi-mode, bidirectional control data bus, a control mode bus for establishing the mode of the bus, and a check interface on which the IFA provides error information. The data interface includes a multi-mode, bidirectional data transfer bus, respective SYNC and ACCEPT lines for transferring time-phased control signals to establish the mode of the data transfer bus, and a parity line to indicate to the IFA the parity of the SYNC and ACCEPT lines.

摘要： A technique for extending the operating range of a flyforward converter to low input voltages. In one aspect, power converter includes a positive input supply rail and a negative input supply rail. A power converter input voltage is to be applied between the positive and negative input supply rails. A flyback energy transfer element having a flyback input winding and a forward energy transfer element having a forward input winding are also included. The flyback and forward input windings are coupled between the positive and negative input supply rails. Voltage control circuitry coupled to the forward energy transfer element is also included to reduce a voltage across the forward input winding, substantially to zero, when the power converter input voltage falls below a first threshold value.
