摘要： A method and apparatus for providing welding-type power is disclosed. It includes an input circuit, a dc bus, an output circuit, and a control module. The input circuit receives power and provides an intermediate signal to the bus. The output circuit receives the dc bus and provides an ac welding-type output. The output circuit includes a half-bridge output inverter with at least first and second switches. The output inverter further includes an output control circuit. The output control circuit provides freewheeling paths that includes control switches, the output, antiparallel diodes. The control module has a four quadrant control module that provides control signals to the half bridge output inverter and provides modulating control signals to the first and second output control switches. The modulating signals cause the output control switches to be turned on and off multiple times to control a rate of change of output current.

摘要： A method and apparatus for providing welding-type power includes an input circuit, a power circuit, and a controller. The input circuit receives input power and provides intermediate power. The power circuit has a power control input with at least one switch that responds to the control input. The power circuit receives the intermediate power and provides welding type output power. The controller has a set point input and a control output. The control output is connected to the power control input. The control circuit also includes a pwm module that responds to the user set point input and provided the control output. The pwm module can include a short duty cycle linearizing module. The pwm module can also include a short duty cycle charging ramp module.
