摘要： An I/O circuit for use with an industrial controller provides an input circuit with low power dissipation through the use of a series connected substantially nonresistance impedance. An AC waveform input (60) activates a light emitting diode (LED) bridge (70) to provide an optical signal (84) which illuminates a photosensitive solid-state switch (86) thereby providing optical isolation (83) between the industrial controller and the controlled process or machine. By using a series connected substantially nonresistance impedance (64), reduced current demand by the input circuit may be realized, which allows reduced power dissipation. As a result, the same circuit allows receiving input signals over a greater range, such as 120 volts AC and 240 volts AC, and allows significantly smaller components with closer spacing for a more compact design.

The synchronous rectification control unit includes a voltage pulse generation circuit (26) configured to measure a current I in a circuit (200) including a power switch (50), and to output a logic high value for a first voltage V1 (28), if the current I has a positive change rate adjacent to a value of zero for the current I, or to output a logic high value for a second voltage V2 (29) if the current I has a negative change rate adjacent to a value of zero for the current I.

摘要： Disclosed is a method of controlling a synchronous rectifier having an input signal having oscillations therein and a switch which is switchable between an open state and a closed state, the method comprising filtering the input signal to produce a filtered signal, comparing the filtered signal with a reference value, and opening the switch in response to the comparison, in which the filtering is active filtering.
The active filtering may be based on determination of the peaks (positive and/or negative) of the signal, either directly, including a quarter period offset, or including decay - or a combination of the above; alternatively, the active filtering may be based on the a smoothing functions such as a switched low-pass filter or a short time integrator.

摘要： A zero-crossing detection circuit includes a comparator and circuitry. The comparator produces an output signal that is indicative of zero-crossing events in an input Alternating Current (AC) waveform. The circuitry may be configured to feed the comparator with first and second rails voltages, and to progressively increase the rails voltages during time intervals derived from the input AC waveform, so as to feed the comparator with target values of the rails voltages in time-proximity to the zero-crossing events. The circuitry may be configured to compensate for an error in detecting the zero crossing events caused by differences in amplitude of the input AC waveform, by correcting the input AC waveform provided to the comparator. The circuitry may be configured to activate the comparator during time intervals preceding respective anticipated times of the zero-crossing events, and to deactivate the comparator at least once during time periods other than the time intervals.
