Information about 1 KVA inverter

[yugamart]

Hi All,

Could anyone help me to find this schematic (inverter 1KVA) and the system too?

Input Power : 48 VDC
frequency : 60 Hz - 120 Hz
Output Power : 230 VAC

I wanted to learn all the system and schematics too.

Thank you

Hi VSMVDD,

Thank you for the info.

But when i looked at schematics, Output VP3 = 12,93 Vdc not 48Vdc.
And How much power input before BR1 1N4001?
Could you advice me?

Thank you.

what is the use of this inverter. if you are going for high frequency you can reduce the size of transformer. you can use simple circuit go for UC3525 Datasheet. use a high volt Mosfet ( IRF250 or similar having high voltage level)

Re: Inverter 1 KVA

This is use for telecommunication power system.

When I look up on BTS (Base Transmission System), they using 48 Vdc (input) for power system.
such as Vsat and Microwave Radio.

* The VSAT System are:

Genset --> Battere (48Vdc) --> Inverter (230 Vac) --> Outdoor Unit (ODU / 230 Vac) --> Antenna.

I am only want to learn from battere to inverter.
Qs+. Why they always use 48 Vdc for their system?

Inverter 1 KVA

hi
with 24 volt battery 1 KVA inverter will work. and if your system requires DC volt you can go for a DC- DC converter. it will reduce the cost because of ferrite core figh frequency

Re: Inverter 1 KVA

Right..

I can convert it with DC to DC converter.

thank you rajudp.
