The invention discloses a control circuit for driving heating by alternating current, related equipment and a related control method. The control method for driving heating by alternating current comprises the following steps: an alternating current rectifier bridge converts alternating current output by an alternating current power supply into direct current with a preset waveform and inputs the direct current into an IGBT (Insulated Gate Bipolar Translator) module; and the IGBT module inputs the direct current with the preset waveform to the connected PTC heater for corresponding heating control based on a preset on-off control strategy. According to the embodiment of the invention, the alternating current of the alternating current power supply externally connected with the control circuit driven by the alternating current for heating can be directly converted into the direct current with the preset waveform through the alternating current rectifier bridge and then input into the IGBT module, and the heating process of the PTC heater connected with the IGBT module is controlled through the IGBT module, so that the cost is low; and when the system is applied to the electric automobile, the existing alternating current power supply capacity of the whole automobile is used for supplying power to the heating process.
本发明公开了交流电驱动加热的控制电路、相关设备及相关控制方法,交流电驱动加热的控制方法包括:交流整流桥将交流电源输出的交流电转换成具有预设波形的直流电后输入至IGBT模块;IGBT模块基于预设的通断控制策略将具有预设波形的直流电输入至所连接的PTC加热器进行相应的加热控制。本发明实施例能直接将交流电驱动加热的控制电路所外接的交流电源的交流电通过交流整流桥转换成具有预设波形的直流电后输入至IGBT模块,通过IGBT模块来控制所连接的PTC加热器的加热过程,不仅实现成本低,而且应用于电动汽车上时借用整车现有的交流供电能力对加热过程供能。
