Abstract
Apparatuses, systems, and/or methods for synchronization of control circuits of welding power supplies are disclosed. In some examples, welding-type power supplies use a modified pulse width modulated (PWM) control signal, in conjunction with certain fail safes, for synchronization of control circuitry. The welding-type power supplies may include conversion circuitry that converts and/or regulates input power to welding-type power. Control circuitry may provide control signals to control the conversion and/or regulation of the input power via the conversion circuitry. The control circuitry may be comprised of a first control circuit and a second control circuit. The first and second control circuit may synchronize their operations using a synchronization signal (e.g., comprised of a modified PWM control signal).
