The invention provides a partitioned PTC heater and a control method, and relates to the field of PTC temperature control. The device comprises a high-voltage power supply module, a control module, an isolation voltage collector, an isolation driver, an isolation current collector, a temperature collection module and a partition heater. The partition heater comprises a plurality of heating partitions, and each heating partition is provided with a plurality of PTC heating core bodies. The isolation voltage collector, the isolation current collector and the temperature collection module respectively collect the voltage value and the current value of the high-voltage power supply module and the temperature of each component, and generate corresponding signals to the control module. And the control module receives a target control signal and each acquisition signal, generates a target PWM control signal and sends the target PWM control signal to the isolation driver, and the isolation driver controls the heating power of the PTC heating core bodies in each heating subarea. Through the partition heating design and the precise closed-loop control, the control precision, the energy efficiency level and the reliability of the heater are improved.

    本申请提供了一种分区PTC加热器及控制方法,涉及PTC温控领域。装置包括高压供电模块、控制模块、隔离电压采集器、隔离驱动器、隔离电流采集器、温度采集模块和分区加热器。分区加热器包括多个加热分区,每个加热分区有若干个PTC加热芯体。隔离电压采集器、隔离电流采集器和温度采集模块分别采集高压供电模块的电压值、电流值和各部件的温度,并生成相应信号给控制模块。控制模块接收目标控制信号和各采集信号,生成目标PWM控制信号给隔离驱动器,由其控制各加热分区中PTC加热芯体的加热功率。本申请通过分区加热设计和精确的闭环控制,提高了加热器的控制精度、能效水平和可靠性。
