Isolated IGBT and SiC Driver Bias Supply Reference Design for Traction-Inverter Applications
Details
| Topologie | LLC Resonanzwandler |
| Eingangsspannung | 24 V |
| Ausgang 1 | 20 V / 0.3 A |
| Ausgang 2 | -4 V / 0.3 A |
Beschreibung
This isolated open-loop LLC transformer driver converter provides dual +20-V and -4-V outputs up to 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. This reference design offers a high level of integration and high efficiency in a compact form factor.
