摘要： A high frequency power source configured to provide a variable voltage output is described such as for use in welding systems. The high frequency power source charges a capacitive storage device. A transformer having a primary winding coupled to the output of the high frequency power source and establishing a resonant frequency signal with the capacitive storage device, and a secondary winding coupled to the welding power supply, superimposes the resonant frequency signals onto the welding power signal of the welding power supply during periods of the resonant rings. By varying the voltage output from the high frequency power source, the high frequency energy delivered to the welding torch can be optimized for a variety of welding applications.

摘要： A charging control circuit for severe battery conditions and an uninterruptible power supply (UPS) system including same are presented. The charging control circuit utilizes both hardware and microprocessor control to allow the UPS to start with depleted or no batteries installed. Initially, the hardware control loops regulate DC bus voltage generation to charge the batteries to a safe level to allow the UPS housekeeping circuitry to wake up and assume control of the UPS operation. Once the microprocessor has awoken, it assumes control of the DC bus and charging of the batteries. If no batteries are installed, the hardware control loop utilizes a fast responding voltage mode control to regulate the DC bus, while a microprocessor-based current mode control is used when batteries are installed. Hardware over voltage control and microprocessor shut off control is also provided.
