摘要： A system and method for generating a weld are provided. A power circuit in communication with a control circuit generates welding output voltage. A voltage reducing circuit in communication with the power circuit generates a reduced output voltage relative to the welding output voltage if the system determines that the welding process is idle for the predefined period of time. The welding output voltage is restored from the reduced voltage if the welding process is restarted.

摘要： Systems, methods, and computer program products for turn on optimization of a driver for one or more light sources are disclosed. A duty cycle value is selected from a table. The selected duty cycle corresponds to the target output current of the driver and has a corresponding voltage. The selected duty cycle is applied to the driver. An output voltage at the light source is measured, and compared to the corresponding voltage of the selected duty cycle to produce a voltage comparison result. Based on the comparison result, the selection of the duty cycle is adjusted. Additionally, an output current of the light source is measured and compared to the target output current, to produce a current comparison result. An adjustment coefficient is applied to a feedback circuit of the driver based thereon, wherein the feedback circuit adjusts a switching frequency of the driver based on the selected duty cycle.

摘要： A digitally compensated hysteretic power supply with enhanced resolution is provided. Such a power supply includes a comparator that is used to compare a load current sense signal with an internal signal generated from a digital-to-analog converter (DAC). A compensation circuit at a DAC input operates to improve current accuracy beyond the given DAC resolution. The current sense signal is converted to its digital equivalent, which is fed to a proportional-integral (PI) compensation loop, which in turn generates a relatively precise high resolution DAC input value. The DAC uses the higher part of the DAC value. The lower part of the DAC value is treated as a duty cycle number, and the DAC output is toggled between two levels at this duty cycle. This toggling generates a current output signal having a value that is the average of the two toggled values.

摘要： Multiple output channel light source power supply circuits, and methods for protecting, are provided. A front end circuit receives an input voltage and provides a regulated front end DC voltage (FEDC). Voltage converter circuits (VCCs) receive the FEDC and provide a separate associated DC output for each associated output channel. A protection switch is coupled between. In its conducting state, the FEDC is coupled to the VCCs. In its non-conducting state, the FEDC is decoupled. A current sense circuit of a current sensor in parallel with a bypass switch is coupled to the VCCs to provide a current sense output representing current through at least one VCC. A controller circuit places the protection switch in the non-conducting state in response to the current sense output. The bypass switch may be placed in a conducting state to shunt current around the current sensor during normal operation to reduce or eliminate inefficiency.
