Title: POWER CONVERSION MODULE
Abstract:
A power conversion module, comprising a power conversion circuit (B), a signal sampling circuit (C), a detection modulation circuit (E), an MCU controller (H), a signal isolation circuit (G), a first operating voltage circuit (D) and a second operating voltage circuit (F). The power conversion module can achieve power transfer and voltage conversion. A zero-crossing detection circuit can achieve real-time synchronization zero-crossing detection of an inputted alternating high-voltage large signal and synchronously output a rectangular pulse wave. The zero-crossing detection circuit can securely isolate the inputted alternating high-voltage large signal from the outputted synchronous pulse low-voltage small signal. The present invention solve the problems that a traditional circuit cannot synchronously detect the zero crossings of the rising and falling edges of the inputted alternating signal, or securely isolate of the detected low-voltage small signal from the inputted alternating high-voltage large signal, and the power conversion module has low overall costs and is secure and reliable.
