The embodiment of the invention relates to a converter circuit. The present specification relates to a circuit for converting from a first AC voltage to a second voltage. The circuit comprises a first thyristor; a first control circuit of the first thyristor; a power factor correction circuit including a coil; and a first circuit configured to convert the third voltage to a fourth DC voltage. The third voltage corresponds to a difference between a potential at a first node connected to an output node of the coil and a reference potential. The fourth DC voltage is configured to power a first control circuit of the first thyristor and is referenced by the same reference potential as the third voltage. 本公开的各实施例涉及转换器电路。本说明书涉及一种用于从第一AC电压转换为第二电压的电路。该电路包括：第一晶闸管；第一晶闸管的第一控制电路；包括线圈的功率因数校正电路；以及被配置为将第三电压转换为第四DC电压的第一电路。第三电压与连接到线圈的输出节点的第一节点处的电位和参考电位之间的差相对应。第四DC电压被配置为向第一晶闸管的第一控制电路供电，并且以与第三电压相同的参考电位为参考。
