Designing Auxiliary Power Supplies for High Efficiency and Low Standby Power
نویسندگان
چکیده
Auxiliary power supplies are required to have low standby power consumption at light-load conditions. These power supplies also require features such as low cost, high efficiency, and a Line Under-Voltage Lockout (UVLO) function to detect the input voltage so the main power supply does not operate at low input voltage ranges. Fairchild’s FSQ510 has been specifically designed for low standby power consumption and valley switching control and is ideal for auxiliary power supplies. This paper outlines a design procedure for an auxiliary power supply using the FSQ510.

The integrated PWM controller features include a proprietary green-mode function that provides off-time modulation to linearly decrease the switching frequency at light-load conditions to minimize standby power consumption. The PWM controller is manufactured using the BiCMOS process to further reduce power consumption. The green and burst modes function with a low operating current (2.5mA in gr...
متن کاملLCC Resonant Multilevel Converter for X-ray Applications
Medical X-ray appliances use high-voltage power supplies that must be able to work with very different energy requirements. Two techniques can be distinguished in X-ray medical imaging: fluoroscopy and radioscopy. The former involves low power radiation with a long exposure time, while radioscopy requires large power during short radiographic exposure times. Since the converter has to be design...
متن کاملStandby - Loss Elimination in Server Power Supply †
In a server power system, a standby converter is required in order to provide the standby output, monitor the system’s status, and communicate with the server power system. Since these functions are always required, losses from the standby converter are produced even though the system operates in normal mode. For these reasons, the losses deteriorate the total efficiency of the system. In this ...
