The large area staring,long linear,infrared devices are used more and more in military,aviation and other fields,so it makes a growing demand for high-power linear Stirling cooler and its driver circuit.The paper introduces the use of FPGA as the main chip for high-power linear Stirling cooler drive circuit with high precision temperature control function.The experiment results indicate that this circuit can improve the temperature control precision to ±0.1 K.And the drive circuit also possesses high stability.
