Boost Converter: Design, Circuit, Equations & More - Power …
WEBApr 20, 2018 — Boost Converter Design. In most any power supply schematic, the inputs are on the left and power flow is towards the load on the right. A boost is a little more than a backwards buck, though, so for a moment, let’s imagine that V-in and V-out in this schematic were reversed. Now, it would change D1 …
Overview of Motor Control in Electric Vehicles
WEBApr 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.
Understanding the EV Powertrain - Power Electronics News
WEBApr 13, 2023 — A typical EV powertrain consists of a battery pack, inverters for power transfer and electric motor (s) through a final reduction drive. For hybrid vehicles and plug-in hybrid vehicles, there are additional components in the powertrain, like an ICE, dedicated transmission and exhaust system. The main components of an EV powertrain are:

Silicon Carbide (SiC): 10 Things to Know - Power Electronics News
WEBMar 17, 2021 — Silicon carbide (SiC), a semiconductor compound consisting of silicon (Si) and carbon (C), belongs to the wide bandgap (WBG) family of materials. Its physical bond is very strong, giving the semiconductor a high mechanical, chemical and thermal stability. The wide band gap and high thermal stability allow SiC devices to be used at junction ...
Inrush Current: Causes, Limiters and Protection Circuits
WEBAug 30, 2018 — During power-on, a high inrush current can occur because the power supply’s link capacitor functions to dampen ripples in the output current. This capacitor acts like a short, causing an inrush of current. The inrush lasts until the capacitor is charged. Length of the inrush current depends upon the power supply and link capacitor.

Power Diode and Rectifier - Power Electronics News
WEBSep 16, 2022 — The power diode. The power diode is a nonlinear passive electronic component composed of two terminals: the anode and the cathode. It makes the electric current pass in only one direction and blocks it completely in the other direction (see Figure 1). It is a semiconductor component and therefore acts as a one-way current switch.
Comparing N-Channel and P-Channel MOSFETs: Which is best for …
WEBMay 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 improved thermal performance ...

WEBFeb 8, 2024 — Most electronics have a power source that provides a higher voltage than the electronics’ typical working voltage. For example, a computer’s power adapter is plugged into a 110 V AC /220 V AC wall socket and draws less than one amp. After various power semiconductors perform a series of step-down voltage conversions, a computer’s processor may eventually work below 1 V DC but may consume ...
