After reverse-engineering the PCB, [bigclivedotcom] concluded that the JW B 1981 must include an onboard bridge rectifier. The only other components on the board are three resistors, a capacitor ...

A diode bridge rectifier on the auxiliary input with its two diode drops further exacerbates the wide range problem, especially at the lower end to 9.6V (= 10.8V – 1.2V). Sometimes the minimum voltage ...

The dual active bridge solution for voltage rectification not only decreases the PCB footprint by 87% and simplifies the BOM but also improves the PD power conversion efficiency by up to 2%.
