Abstract: A power supply for welding, cutting and similar operations includes a dual two-switch forward converter. The converter has two inverter circuits coupled in parallel but controlled to provide output power in an interleaved fashion. To avoid “walking” of the circuits (which could result in different duty cycles and imbalance of the load sharing), control signals are determined and applied to a first of the inverter circuits, and “on” times of the first circuit is monitored, such as by augmenting a counter to determine the number of clock cycles the first circuit is “on”. The same duration is then used for commanding output from the second inverter circuit. The duty cycles of both circuits is thus ensured to be the same regardless of changes in the total output power.

Abstract: A power supply for welding, cutting and similar operations includes one or more power converters that are controlled by PWM signals applied by control circuitry. The signals may be applied for a period greater than 50% duty cycle. The duty cycle may be determined by monitoring power or current draw by a welding or cutting operation load. Where more than one converters is used, each may have the same or different duty cycles, and each may be extended beyond a 50% maximum.
Abstract translation: 用于焊接，切割和类似操作的电源包括由控制电路施加的PWM信号控制的一个或多个功率转换器。 信号可以施加大于50％占空比的周期。 占空比可以通过焊接或切割操作负载的监视功率或电流消耗来确定。 在使用多个转换器的情况下，每个转换器可能具有相同或不同的占空比，并且每个可以延伸超过50％的最大值。

Abstract translation: 用于焊接，切割和类似操作的电源包括双双开关正转变换器。 该转换器具有并联耦合的两个逆变器电路，但被控制以交替的方式提供输出功率。 为了避免电路的“走动”（这可能导致不同的占空比和负载共享的不平衡），控制信号被确定并施加到第一个反相器电路，并且监视第一电路的“接通”时间， 例如通过增加计数器来确定第一电路“接通”的时钟周期数。 然后使用相同的持续时间来指示来自第二反相器电路的输出。 因此，无论总输出功率的变化如何，两个电路的占空比被确保相同。

Abstract: A method and apparatus for providing welding-type power is disclosed. The system includes a power supply, a wire feeder, and a controller. The wire feed speed is reduced when the input current exceeds a value to prevent tripping circuit breakers on the power line the welder is connected to. The speed reduction is based on an average current draw exceeding a threshold. The output voltage is reduced if the input current exceeds a second threshold.
