Systems and methods to control welding processes using a voltage-controlled control loop

A method to control a welding-type power supply, comprising:

• controlling, via control circuitry, power conversion circuitry to convert input power to welding-type power based on a voltage-controlled control loop;
• monitoring, via a voltage sensor, an output voltage of the power conversion circuitry;
• and
• in response to detecting that the output voltage is less than a threshold voltage:
• during a first state, controlling the voltage-controlled control loop based on a first value of a control parameter of the voltage-controlled control loop to increase a response rate of the voltage-controlled control loop;
• and
• during a second state following the first state, controlling the voltage-controlled control loop based on a second value of the control parameter, wherein the second value of the control parameter causes a reduction in energy output by the power conversion circuitry relative to the first state.

A non-transitory machine readable storage medium comprising machine readable instructions which, when executed by a logic circuit, cause the logic circuit to at least:

• control power conversion circuitry to convert input power to welding-type power based on a voltage-controlled control loop;
• monitor, via a voltage sensor, an output voltage of the power conversion circuitry;
• and
• in response to detecting that the output voltage is less than a threshold voltage:
• during a first state, control the voltage-controlled control loop based on a first value of a control parameter of the voltage-controlled control loop to increase a response rate of the voltage-controlled control loop;
• and
• during a second state following the first state, control the voltage-controlled control loop based on a second value of the control parameter, wherein the second value of the control parameter causes a reduction in energy output by the power conversion circuitry relative to the first state.
