I need to design a 150watt inverter at 400Hz for running my communications receiver .
The same is old army unit running at 28VDC battery ..and needs 20 VDC to 35 VDC range ..
The waveform is pure sine distortion-less for low noise generation.
 

That sounds very inefficient even for an old Army receiver. I assume it uses vacuum tubes to need so much power, can you rewire the heater filaments so they work off lower voltage then use a HT generator using a simple inverter?

No way..It is actually not a plain recvr but a transceiver with RF power amplifier for uplinking to dish antenna for short wave communications .
The power amp has 65watt power reqts .THE bias curents are 100mA and the reception is 10watts ,audio power is 25watts max.

That's not what you put in your first message. Being a transceiver rather than just a receiver makes a huge difference.
Does it need to be 400Hz?

There may be other applications of the Inverter once it is submitted to army defence units.
The approvals need to be taken from DGQA group.
 

Been a long time since any expert responded to my requirements of Pure sine wave 400Hz /150watt inverter design ...
Await circuit design help along with available components .
