摘要： Enhanced power factor correction for a welding-based power supply includes a controller that tracks a rectified input voltage waveform and detects zero-crossing events therein. The controller generates an ideal sinusoidal current reference signal synchronized by expected zero-crossings in the supplied power. The reference signal is used in a current control loop within the controller to control the power electronics such that the waveform of the current drawn by the power supply matches the waveform of the input voltage. The frequency of the supplied power may be calculated using the expected zero-crossings and used to adjust the expected zero-crossings.

摘要： In accordance with the present invention a power supply for providing an ac/dc output to a load is disclosed. The power supply includes a first source of dc power and an inverter that provides an ac output to the load. A second source of dc power is provided and selectably connects the first and second sources of dc power in series with the load when the output current reverses. In one embodiment the power sources are connected in series with every output current reversal. The first source of dc power is controllable and the magnitude of the dc current is responsive to a current reference signal. A control circuit provides the current reference signal, wherein the current reference signal is pulsed immediately prior to the ac output reversing polarity. The first source of dc power source preferably includes a buck converter that is switched at a variable frequency, depending upon the desired output current. In the event the user selects either an ac or dc electrode negative output a period of electrode positive dc energy is provided at start up to help establish the arc.
