| 英文摘要 | The present invention provides an optical transmitter with a forward controlled Peltier driver. The temperature sensor generates a monitoring signal Sm. The comparator compares this monitored signal Sm with the target temperature signal St to generated the temperature difference signal Sn. The limiter restricts this difference signal Sn between the positive and negative maximum of the periodic signal Sw to generate the limiting signal Sa. The second comparator compares this limiting signal Sa with the periodic signal Sw to generate the control signal. The PWM signal generator, responding to this limiting signal Sa, generates a plurality of PWM signals, Sg1 to Sg4. The H-bridge including four transistors and two inductors, responding to this PWM signals, controls the direction of the current flowing in the Peltier device. The magnitude of the current can be determined by the duty ratio of the PWM signals. |
