    • A method and apparatus provides welding-type power and preferably includes a removable battery or other energy storage device, a converter connected to the battery, and a controller. The controller may have a CV and/or a CSC and/or an AC weld control module, and/or an ac auxiliary control module. The converter is a boost converter, a buck converter, a cuk converter, a forward converter, an inverter, a bridge converter, and/or a resonant converter. The controller may include a battery charging control module, and may have one or more charging schedules, and/or data for stored charge, thermal information, expected life of the battery, maximum amp-hour charge for the battery, maximum charging current and/or feedback. The battery charging schedules may include at least 3 phases, such as a phase of increasing voltage and a phase of decreasing current, a substantially constant power phase. The controller can wirelessly provide data to a display or pda. A generator may provide power to the battery, charger, and/or the weld. It can include a vehicle and use its dc power system.
    • 一种方法和装置提供焊接型电力,并且优选地包括可拆卸电池或其他能量存储装置,连接到电池的转换器和控制器。 控制器可以具有CV和/或CSC和/或AC焊接控制模块和/或AC辅助控制模块。 转换器是升压转换器,降压转换器,cuk转换器,正激转换器,逆变器,桥式转换器和/或谐振转换器。 控制器可以包括电池充电控制模块,并且可以具有一个或多个充电时间表和/或用于存储的电荷,热信息,电池的预期寿命,电池的最大安培小时电量,最大充电电流和/ 或反馈。 电池充电时间表可以包括至少3个相位,例如增加电压的相位和减小电流的相位,基本上恒定的电力相位。 控制器可以无线地向显示器或pda提供数据。 发电机可以为电池,充电器和/或焊接提供电力。 它可以包括车辆并使用其直流电源系统。
