The Control of Wind Generators

The functions of Hummer Controlling Unit are 1.to rectify to charge, 2.to protect the battery from overcharge, 3. to protect the battery from over unloading, 4. to unload the extra power when the battery is full, 5. to invert DC to AC

Hummer controlling unit is not only multifunctional as well as high qualified and high reliable. Hummer wind-solar controller (for wind ?solar PV hybrid system) is a three-in-one system integrated the controlling of battery charging/discharging, inverting .

Controlling (charge and discharge) function:

AC generated by wind-driven generator and DC from the solar energy can charge to battery under the function of controller.

when the volume of battery has not been filled absolutely , the function of controller is to charge the battery maximally, controlling the electricity of the wind-driven generator and the solar energy have sent out, when the battery is filled, keeping the battery at a floating condition.

>When discharging voltage close to the overcharged point, the controller will alarm a signal of insufficient electricity, cutting off the storage battery's the return circuit to protect the storage battery.

A rectified bridge is needed to exchange AC to DC, then charge DC to the storage battery. The common rectifying valve pressure reaches as high as 0.7v, when big electric current charges, the rectified bridge heat fiercely. E.g. 300W wind turbine reaches 300W, the rectified bridge will loses 30W because of heating, that will lead to only 270W can be derived when 300W's electricity is sent out by wind turbine, the phenomenon of rectified bridge is burned appearing frequently because of heating ,when the big electric current charges continually.

Our hummer controller selects 16 Low Power Schottky Diodes   parallel combination to make the tube's pressure low to 0.1v. 30W's electricity loses when the utilizing of the common rectified bridge, but only 5W loses when our hummer rectifier parts are used, little consumption of electricity results to little self-heat.

At the same time, the professional all know the cost of 16 Low Power Schottky Diodes has been higher than the same rank inverter's market selling price.

The high cost trades the high quality, high reliable, the hummer deserve do it!

Inverting function:

The hummer wind-solar hybrid system's invert power is mainly used for wind power system and solar energy system..

In the market, the common inverter all uses ring transformer with big volume and heavy weight, that consumes the electricity very excessively. When the inverter outputs 300W power, Approximately 60W power has been consumed as inverter's self-heat, when the inverter outputs 300W power, Therefore in the market the common inverter burnt down often takes place.

Our hummer inverter is applied for high frequency switching power supply technology, not only the weight is light, and the efficiency is high, consuming few electricity, the transformer adopt ?s ultra microlite soft magnet transformer ?, which gives off heat extremely few. When outputs 300W AC, only 25W's electricity lost for inverter , and the perfect protective measures are adopted to guarantee the high reliability of inverter.

If the hummer wind turbine is matched the ordinary battery charger and inverter sold in the market, although much electricity is generated, much is consumed by charger and inverter -- the lost electricity can reach 35W because of the ordinary rectified bridge's self-heat, when 350W wind turbine reaches 350W power, then outputs 300W power, 60W is lost because of the inverter- own giving off heat , so It is impossible that an ordinary 300W inverter can drive a freezer in summer.

However our hummer 350W wind turbine is allocated with special-purposed inverter-controller ,not only is reliable, but the function is also formidable with a low self-consumption (only 5W is lost on rectifier part, 25W is lost on inverter part), can drive big color TV or 400W's water pump or 400W electric cooker, of course can drive refrigerator or freezer.

High quality life can be brought with our hummer special-purposed control-inverter, absolutely is compactable to your money !
