The way that high density temperature control impacted on TEC by MCU application.TEC temperature is collected and accumulated by MCU usage,so as to produce control impulse after PID calculation.Then,H-bridge control waveform generated by CPLD.Finally good control of temperature owed to effect control of current direction and circulation time.
