PMP23661
500W, 12V-output, ZVS full bridge with current-doubler converter reference design
PMP23661
概述
This reference design is a full-bridge topology that is comprised of a TPS7H5005-SEP referenced on secondary ground that controls four TPS7H6005-SEP half-bridge gate drivers. The two drivers referenced to the primary side operate in PWM mode which allows for the design to achieve zero-voltage switching (ZVS) at higher loading conditions. On the secondary side the other driver controls a pair of secondary rectifiers in a current-doubler configuration to further improve the conversion efficiency. In this design the controller, half-bridge drivers and GaN field-effect transistors (FET) are chosen to meet radiation for geostationary orbit (GEO). These components can be swapped out to meet other mission specifications.
特性
- Current-doubler output configuration
- < 1% voltage ripple on output
- >90% efficiency at full load across input voltage
- Secondary-side controller for faster control loop
- GEO class radiation performance
