Power Supply Design Notes: How to Measure Ripple
Oct 10, 2020 · Select the “AC voltage” mode by turning the tester knob. The meter will only measure the AC component of the signal, the ripple voltage, if present. The display shows the measured value of the ripple voltage amplitude. If it shows the value 0.00 mV it means that, most likely, the ripple is absent.
Overview of Motor Control in Electric Vehicles
Apr 20, 2023 · The Motor Control Unit (MCU) is an electronic module that interfaces between the batteries (DC power sources) and the motor (AC or BLDC). Its main task is to control the EV’s speed and acceleration based on throttle input. The main activities performed by an MCU are the following: Control the motor torque and speed.

Comparing N-Channel and P-Channel MOSFETs: Which is best for …
May 28, 2024 · To achieve a similar on-state resistance R DS(on) as n-channel MOSFETs, p-channel MOSFETs require a two to three-times larger die size. As a result, in more high-current applications, where low conduction losses are critical, the large die p-channel MOSFETs with very low R DS(on) are not the optimal choice.. While the p-channel device’s larger chip size offers …
USB-PD 3.2: Key Updates and Impact - Power Electronics News
May 29, 2024 · AVS requirements and corrosion mitigation are the major updates to the USB-C and USB-PD specifications. AVS is mandatory for certain power delivery ranges (27–100 W) in USB-PD 3.2.
