PORTABLE HYBRID WELDING MODULE WITH BIDIRECTIONAL DC-DC CONVERTER CIRCUIT; HYBRID WELDING SYSTEMS WITH SUCH PORTABLE WELDING POWER SUPPLY

摘要

Hybrid welding systems (100) and portable hybrid welding modules (102) are disclosed. An example portable welding power supply (102) includes an output converter circuit (110) to convert direct current (DC) power to welding power, the DC power comprising at least one of DC input power or converted battery power. The portable welding power supply (102) also includes a battery (106) and a bidirectional DC-DC converter circuit (112) configured to receive the DC input power and coupled to the battery (106). The portable welding power supply (102) also includes a control circuit (114) configured to control the output converter (110) to output the welding power, control the bidirectional DC-DC converter circuit (112) to convert the DC input power to charge the battery (106), and control the bidirectional DC-DC converter circuit (112) to convert power from the battery (106) to provide the battery power to the output converter (110).
