Technology Q&A
 01. What kind of certification is needed for the wireless power charger system ? |
Ans. |
The Tx of current design is DC system, it needs to be connected with city power through transformer, so, the security portion is complete by transformer, and the wireless power transfer system needs to pass the EMC regulations. |
|
 |
02. What is the efficiency and power of FDT wireless power charger?
|
Ans. |
Current mass production product is set in 70. However, it can be tailored by customers’ requests. |
|
|
03. What is the size of the Rx module?
|
Ans. |
Based on 5V-1A output, the size of Rx PCB is around/above 8 cm, and the oil area is around/above 12 cm .
|
|
|
04. What is the price of FDT module? |
Ans. |
If calculated by Rx side output 5V-1A, cost will be around US$15. Detailed price will change depending on different design.
|
|
|
05. What is the nduction distance of FDT wireless power charger system? |
Ans. |
The distance is set by 1mm-20mm ain purpose and consideration is pass through EMC certification (?).
|
|
|
06. What is frequency of FDT wireless power charger system? |
Ans. |
The frequency is 125KHz,and it will be adjusted automatically by system.
|
|
|
07. What is stand-by current? |
Ans. |
The current is 6mA@9V,and its mean standby current is 0.054W. |
|
|
08. What is metal reaction against Tx? |
Ans. |
When Tx transmits the data to Rx side and detects that there is not Rx, it will automatically shut down. Hence, at Rx side, even putting a metal on it, it will have no reaction. |
|
|
09. What is the transmission speed? |
Ans. |
The transmission rate is 8Kbps, and it is mainly used for controlling power charging operation.
