Understanding, Measuring, and Reducing Output Voltage Ripple
This can be achieved by increasing the switching frequency (tradeoff is more switching losses, hotter solution and lower efficiency) or by increasing the inductance (tradeoff is larger physical size).
Methods for reducing ripple voltage
In practical applications, appropriate methods can be selected based on specific needs to reduce ripple voltage and improve the stability and reliability of the power supply.
(PDF) Ripple Attenuation and Aliasing Suppression in Multisampling
Previous studies have demonstrated that a moving average filter (MAF) or improved repetitive filter (IRF) can effectively remove the high-frequency ripple.
High-bandwidth modules quell disruption of line ripple rejection
Another integral component in the power architecture is the traction inverter, which is necessary to convert the battery''s DC output to AC to power the EV motor. The traction inverter creates unwanted
Methods for Reducing Ripple and Noise in Converter

The optimization of torque ripple reduction by using DTC-multilevel
However, high switching frequencies and torque ripple can occur, particularly at extreme operating conditions (low-speed) due to the inappropriate selection of voltage vector in the DTC system.
Four ways to reduce the "ripple and noise" of switching
The ultra-high frequency resonant noise can be reduced by selecting soft recovery diodes, switching tubes with small junction capacitance, and reducing the wiring length.
Ripple Reduction Techniques for Stable Power Conversion
Linear regulators can provide high ripple reduction. Filtering with a low-pass filter or a notch filter is a strategy for addressing the ripple frequency. This is preferable in DC regulators, especially when
Managing high voltage line ripple rejection
Electric vehicle HV bus overview and inverter ripple High voltage ripple occurs on high voltage bus during propulsion and regeneration as a result of inverter''s (PIM) operation.
Ripple Reduction Techniques for Stable Power Conversion
Regulation with An LDOFilteringControl with FeedbackLarger Inductor and Higher PWM FrequencyMultiphase RegulationA multiphased converter implements multiple switching stages in parallel, but separated in phase. While these circuits can be much more complex, they act like a single-stage regulator with a much larger switching frequency and inductor. The result is greatly reduced ripple measured on the output. These regulators can be used with DC loads or high f...See more on resources.system-analysis.cadence IEEE Xplore
