Pre-regulated isolated driver bias supply reference design for traction-inverter applications
Overview
| Topology | LLC Resonant Converter |
| Output 1 | 18 V |
| IC revision | B |
Description
This pre-regulated isolated open-loop LLC transformer driver converter reference design provides four 18-V outputs up to a total of 6 W for traction-inverter applications. The LLC topology allows the transformer to have significant leakage inductance, but a much smaller primary-secondary capacitance, which significantly reduces common-mode current injection through the bias transformer. The boost pre-regulator is designed to provide 7.5 W to the LLC converter, which can support a maximum of 6-W output.
Features
- Small open-loop solution size drives four outputs
- Boost stage provides regulated input to LLC
- Compact PCB size (83 mm x 81 mm)
Typical applications
- Traction inverter-high voltage
