Analog Isolated Multilevel Quantizer for Voltage Sensing while Maintaining Galvanic Isolation
A low-power, compact device for performing measurements in electrical systems with isolated voltage domains is proposed. Isolated measurements are required in numerous applications. For instance, a measurement of the bus voltage for a system with a high supply voltage and lower isolated local voltage level may be needed for system health monitoring and
