Dual-output bias power supply reference design for inverter and motor drive applications
Description
This isolated primary-side regulated (PSR) flyback converter reference design provides dual +15-V outputs at 100 mA each. It was designed to provide bias power for a rotor coil excitation gate driver in motor/ inverter applications. The isolated output voltage is sampled from the primary-side flyback voltage eliminating the need for an optocoupler: voltage reference or third winding from the transformer for output voltage regulation. It offers a high level of integration and high efficiency in a compact form factor.
Features
- Primary-side regulation eliminates optocoupler or transformer bias winding which results is a compact sizeExcellent balanced load output voltage regulation (Excellent unbalanced load output voltage regulation (High efficiency (>90% from 50% - 100% loading)LM5180 controller integrates FET and minimizes external components
Applications
- Traction inverter-high voltage
