Descripción
- TIDA-00173, 400-V to 690-V AC Input, 50-W Flyback Isolated Power Supply Reference Design for Motor Drives. This reference design provides isolated +24V (45W), 16 V (4.5W), and +6V (0.5W) outputs to power the control electronics in variable speed drives. The power supply can be either powered directly from 3-phase AC mains (380Vac to 690Vac) or can be powered from the DC-link voltage (400Vdc to 1200Vdc). This design uses a quasi-resonant flyback topology and is rated for 50-Watt total output power. The line and load regulation of the power supply is designed to be within 5% using primary-side regulation (eliminating costly feedback components)
