Charger module and circuit

The invention relates to a charger module and a circuit. The charger module is integrated with a charger control layer, a charger low-voltage layer and a charger high-voltage layer from top to bottomin sequence, wherein the charger control layer is used for providing an external control interface, supplying power to a sensor low-voltage power supply and collecting and controlling a charger controller; the charger low-voltage layer is used for providing high-frequency rectification output filtering and EMI electromagnetic compatibility; the charger high-voltage layer is used for providing high-voltage input filtering and high-frequency soft switch DC/DC conversion; and all the layers are isolated through isolation plates. The charger module is divided into the charger control layer, the charger low-voltage layer and the charger high-voltage layer based on functions and voltage grades, so the space layout is reasonable; meanwhile, the high-voltage thick copper PCB integrated design is adopted, and scattered ele
