12 V - 5 W isolated flyback converter based on VIPer122LS
This design uses LM3S811 as the processor of the lubricating oil dielectric constant detection device, designs the AD5933 impedance measurement circuit, extracts capacitive reactance information from the impedance data, and calculates the change in the lubricating oil dielectric constant based on the change in capacitance to achieve lubrication control. Test the dielectric constant of oil and record the data to find out the change pattern between lubricating oil quality and dielectric constant.

Dual Output Isolated PSR Flyback Converter Using VIPER267KDTR for Smart Instruments and PLC Systems
ST1S12XX based 0.7 A/1.2 V synchronous buck converter with enable function
The overall structure of this design is roughly composed of a main control module, a current signal sampling module, a power module and a serial port output module. In this article, the main control chip uses a microcontroller model STM32F103RC, which makes the structure as small as possible while ensuring the current sampling accuracy. It is as simple as possible, avoids complex and changeable circuit layout, is more convenient for PCB board production, and is relatively low-cost. Among them, in the design of the sampling conditioning circuit, a current transformer is used to sample the current signal.
