Why ASR?

The AC to DC conversion of electricity is required in almost all electrical machines. The diode passive rectifier is the most common solution for achieving this conversion. Because the diode is based on the P-N junction structure, there are many drawbacks in electrical applications. One such drawback is inefficiency in high current applications, which requires a large heatsink or cooling fan. Another disadvantage is non-linearity in circuits, causing harmonic interferences to the service utility.

ASR will bring a revolutionary solution to the process of AC/DC conversion. It contains three components: a power MOSFET, a current detection unit (Hall effect switch with electromagnetic concentrator), and a half bridge driver. This is a configuration that is justified by the following points:

• The power MOSFET has superior characteristics over diode. It switches very fast and it has very low Ohm resistance when it is in the ON state.
• The current detection unit acts quickly and reliably. It is triggered by pre-design threshold current in a real time.
• The floating voltage driver will allow N channel power MOSFET to config single phase H bridge or three phase H bridge rectifier in many circuits.

The contributions to humanity that stem from this technology are substantial and worthy of our consideration. 

• It will increase the efficiency of an automotive alternator by 10 percent which means a lot of fuel saving, performance increasing without the additional cost.
• It will increase the efficiency of standard switching power supply (5V, 12V) by 20 percent which saves electricity.
• It can save a lots of heat sink metal, eliminate the cooling fan. The equipment will be more reliable because of cool operation.

ASR is an intelligent, green technology that has the potential to pave the way to a better future for all of us.
