Hi,
Am a new user and just logged in.Could any one help me out with a dc -dc converter design. the specs are as follows.
Input Voltage 12-48V DC
Output Voltage : 450V DC slightly adjustable using MT pot.
Power: 3KW
Topology : Full Bridge input stage ,step up transformer, rectifier , output filter and PWM control
Isolation : HF Transformer isolation
Switching Frequency : 40Khz Or UPWARDS
Efficiency : minimum 90%
o/p regulation:1% from no load to full load

kind regards,
culy69

TI is having kind of solutions. You can use a DSP for DC to high frequency AC conversion and then to DC power. The DSP will take care of your PWM.
