Pure Sine Power Inverter 2KW - AIMS Power

AIMS Pure Sine Wave Power Inverters provide reliable transformation of DC power from a battery into AC power that can then be used to run lights computers, printers and even medical equipment.

2000 Watt Pure Sine Power Inverter

This is an industrial-grade unit with the ability to withstand surges of up to 6000 watts for 20 seconds, and  it achieves this by virtue of its direct connect terminal block. This feature is one of the more sought-after in the inverter industry, allowing users to surpass the 1,500 watt maximum output of a GFCI outlet that would typically be seen on an inverter.



The 2000 watt 48 volt low frequency AIMS Power inverter charger transforms DC (direct current) power, produced by solar panels and stored by batteries, into AC (alternating current) electricity that can be used to run most all tools and appliances. This inverter also has a built in AC-to-DC battery converter charger, which allows users to recharge their battery bank from an AC source such as a fuel-powered generator, shore power or a regular outlet at home.

Battery Boost Circuits

(This is a thread of my Google Talk many years ago - you will be able to notice text communication is quite difficult. sometimes even verbal expression will not specify the need, We need clear drawings and specs)

Sam: I was going thrugh some IC like MAX8880/MAX8881, can u help me with using that with input from my batteries?

dapj: let me see

Sam: It's datasheet says that Supply current [Iin] = 10uA max does it mean it will draw a max of 10uA from my battery?

dapj: it looks like it will work from 2.5 to 12V and it can give you a 5v out 200ma

Sam: Exactly!

dapj: is 5V enough 200mA too, but it cannot boost voltage

Sam: my concern is with my input. What about using rechargeable batteries [4x1, 2100mAh] to act as input to this IC. will it consume 10uA if I do so while my load to the output may vary from 100mA to 200uA



dapj: if you want 5V you need to feed this atleast 5.5V this chip does not consume anything (the uA is Standby consumption )but it is not a voltage doublet or a charge pump

Step-Up/Step-Down Converter Features Ultra-Low Quiescent Current

Sam: OK, I need to feed it anything between 5.5 -12V, Do we get recharge battery near about 2V, 2100mA

dapj - a 12 v battery can be recharged when 11.8V is reached it may charge upto 12.8 V in Li ion

Fast, smart NiCD/NiMh battery charger - The MAX713 is designed for NiCd batteries, while the 712 is for NiMh batteries.

Fuel cells have been around longer than most batteries - the principle of the fuel cell was discovered in 1839 by Sir William Grove. They generate electricity from the reaction of hydrogen with oxygen to form water in a process which is the reverse of electrolysis.

Battery and Energy Technologies

The fuel cell relies on a basic oxidation/reduction reaction, as with a battery, but the reaction takes place on the fuel rather than the electrodes. The fuel cell produces electricity as long as the cell receives a supply of fuel and can dispose of the oxidized old fuel .

High Efficiency Step Down Isolated Supply

60W AC-DC adapter, synchronous rectification, fixed frequency current mode PWM controller. Very Low Quiescent Burden, Efficiency above 85%. That's Green.

STMicroelectronics - EVALSTSR30-60W. Synchronous rectification using L6668 and STSR30.


EVALSTSR30-60W: 60W AC-DC adapter

The converter works in both Continuous and Discontinuous conduction mode depending on the input voltage (the circuit has a wide input voltage range) and the output load. The 68-kHz switching frequency provides a good compromise between the transformer size and the harmonics of the switching frequency, optimizing input filter.

The input section includes protection elements (varistor, fuse and NTC for inrush current limiting), a standard Pi-filter for EMC suppression, a bridge and an electrolytic bulk capacitor as the front-end AC-DC converter. The transformer is a layer type, uses a standard ETD34 ferrite core and is designed to have a reflected voltage of 95V. The power MOS is a 700V - 1Ω and a transil clamp network is used for leakage inductance demagnetization.
