POWER CALCULATING METHOD ADOPTED IN WIRELESS POWER SYSTEM

摘要

The present invention relates to a power calculating method adopted in a wireless power system comprising the stages of: firstly obtaining a current root-mean-square (RMS) value by calculating root square of the result of multi point sampling for input or output current of a voltage stabilizing unit; obtaining a voltage RMS value by calculating root square of the result of an execution of multi point sampling for input or output voltage of the voltage stabilizing unit; obtaining a power value of the voltage stabilizing unit by multiplying the current RMS value to the voltage RMS value and then multiplying a cosine value of a narrow angle; additionally obtaining a receiving power value by dividing the power value of the voltage stabilizing unit with a power receiving terminal RMS value; and finally transferring the receiving power value to a power transmission terminal of a wireless power system.
