Isolated bias power supply reference designs using four different topologies
Overview
| Topology | ADC |
| Input voltage | 15 V |
| IC revision | 1 |
Description
This reference design showcases four isolated bias power supply designs using different topologies as PSR flyback, push-pull, LLC resonant and isolated DCDC module. These topologies provide specific benefits but at the same time come with trade-offs. An ample comparison of these topologies is done using four hardware designs while keeping the electrical paramaeters as similar as possible. The input and output voltage of these designs are 15V and maximum load current is 100mA.
Features
- Isolated bias power supply design using different topologies like PSR-flyback, Push-pull, Isolated DCDC module and LLC resonant
- Ample comparsion of different isolated bias power supply topologies
- Comparative analysis using similar electrical parameters in circuit designs for different topologies
Typical applications
- Automotive traction inverter & motor control, Automotive on-board charger (OBC), Automotive DC/DC converter
- UPS and solar inverters, Industrial motors, elevators and escalators, GaN, IGBT and SiC gate transformer driver bias supply
