摘要： A method and an apparatus for limiting the peak power consumed by a thermal recorder (44) connected to portable battery-powered equipment. The battery-powered equipment is designed with a filter (58) and an electronic circuit breaker (56). A circuit breaker current sense resistor (60) and an output capacitor (62) form an RC filter and provide a large current reservoir for the thermal recorder which averages the peak current demands seen at the circuit input. The electronic circuit breaker provides a current limit function and will not allow a current greater than a predetermined amperage level to be drawn. The thermal recorder has a CPU which provides pulses to a thermal print head in dependence on data incorporated in a pulse-width limit table. The values in the pulse-width limit table can be substituted for calculated pulse widths that would produce peak currents large enough to trip the circuit breaker.
