As a kind of power equipment, AC current source is becoming widely used in the application of electronic systems. With the development of electronic technology, a higher request of parameters is put forward, such as the output range, precision and stability of the current. In order to achieve these requirements, a sinusoidal AC current source with ATxmega128A1 chip as micro controller is designed. With the closed-loop control function, it can automatically adjust the output current to provide stable output current value within the range of parameter settings, according to the variation of load. It has been applied to the plant seedlings magnetoelectric compound induction breeding control system. The operation results show that the system has practical ad- vantages including high parameter precision, small waveform distortion, convenient control and adjustment. It is applicable to higher requirement of current stability and reliability, so it has very high application value and good market prospects.
