680639-2 is a self-contained linear power converter that uniquely combines several components into a single package. The device is designed to meet the needs of various applications such as power factor correction, motor control, and UPS. It requires an external voltage supply, typically a DC power supply, and can provide an output voltage that is adjustable over a wide range. The device can be used for driving motors, pumps, and other linear loads.

680639-2 employs resonant power conversion technique along with the combination of one-two current source oscillator, rectifier, and transformer. It utilizes an LC resonator as the switching device, resulting in zero voltage switching and zero current switching of the switching device. The resonator utilizes harmonic resonance to maintain switching operation over a wide range of output load conditions and input voltages. This technique allows a compact, efficient converter with low EMI and low switching loss.

The main component of the 680639-2 is the current source oscillator which operates in two stages, a wave shaping stage, and a power amplification stage. The wave shaping stage uses a MOSFET to transform the DC input voltage into a sinusoidal waveform, which is then amplified by a transformer. The power amplification stage consists of a controlled rectifier which converts the sinusoidal waveform to a DC output voltage. The transformer is used to maintain the output voltage in the desired range. Additionally, the rectifier also acts as a current limiter, preventing the current from exceeding the peak limit.

The 680639-2 is also equipped with a self-protection circuit which automatically shuts down the device in case of overcurrent, overvoltage, or overtemperature. This ensures the safe operation of the device and prevents any damage to the components. In terms of application, 680639-2 can be used in a variety of situations like DC-to-DC converters, motor drives, ...etc. It can also be used in uninterruptible power supplies to provide a stable output power even during mains power fluctuations.

In short, 680639-2 is a self-contained linear power converter that is highly efficient, delivers a wide range of adjustable output voltage, features low EMI and low switching loss, and automatically shuts down in case of overcurrent, overvoltage, or overtemperature. It can be used for applications such as motor control, DC-to-DC converters, UPS, and various linear load applications.
