Power-supply requirements for three-phase electric-energy meters used in industrial applications have grown quickly in recent years. For example, distributed factory automation requirements for monitoring power consumption have driven the adoption of wireless communications in high-end electric-energy meters. In such meters, the power supply may need to deliver up to 20W of regulated low-voltage dc output, while operating from mains voltages as high as 690 Vac. The electric-energy meter manufacturer typically would like to implement such power supplies as inexpensively and flexibly as possible. Furthermore, the manufacturer may wish to reuse the same approach, topology and semiconductors it employs in single-phase electric-energy meters, which operate at much lower ac line voltages. A quasi-resonant flyback converter design that incorporates high-voltage bipolar transistors can meet these seemingly conflicting requirements. In order to meet more customers' requirements, we Sinrace will constantly do our best on such special area. |
