Role of Power Electronic Converters in Electric Vehicles

PECs are typically used in three main systems of an electric vehicle: battery charging, powertrain, and regenerative braking. They are primarily needed for electrical power regulation in these systems.

Additionally, PECs facilitate the operation of various voltage ratings for various electrical loads, including low voltage electronic loads like sensors, tacho meters, and communication systems, as well as high voltage electrical loads like power windows, air conditioning, car interior lighting, electric power steering, and auto start/stop.

The block diagram of a typical electric vehicle with power supply system is shown below:

Power Electronics and Battery Charging System

The Battery charging system plays a major role in design and operation of electric vehicles. During the charging and discharging process, control, conversion, and management of electrical energy come from the power electronics. Two types of charging are possible in electric vehicles – On-board charging and off-board charging.

In Onboard charging, AC-DC converter (Rectifier) which is a type of PEC is used to convert the AC voltage from the three phase AC grid to a DC voltage suitable for charging the vehicle’s batteries, whereas in Off-board charging, DC fast-charging is included.

The PECs in these systems convert the AC supply from three phase AC grid into a high-voltage DC output, which can directly charge the vehicle’s batteries bypassing the . Apart from conversion, PECs regulate the charging rate of battery with the help of advanced control strategies.

While offboard chargers or DC fast charging stations are located outside electric vehicles at locations like parking garages, retail centres, hospitals, and charging stations, onboard chargers and battery storage systems are installed inside these vehicles.

PECs are also essential components of Battery Management Systems (BMS). These systems monitor the health, safety, and optimal operation of the battery pack, ensuring its extended life and effective energy use. EV batteries can be charged quickly and effectively while remaining within their safe operating limits due to advanced charging systems controlled by power electronics.

Power Electronics and Powertrain

For bidirectional power flow between a grid and a vehicle, a Bidirectional DC-DC converter with boost and buck modes are utilized in the powertrain. Both boost and buck modes can be used with a bidirectional DC-DC converter by choosing the appropriate switching patterns.

When in boost mode, it boosts the voltage from battery to a high voltage required for DC bus. This high-voltage DC bus has a voltage level of between 400 and 750 V. The vehicle’s batteries can be recharged when the electric motor’s generated voltage is bucked (stepped down) through a bidirectional DC-DC converter during regenerative braking.

The process of converting the vehicle’s kinetic energy—which is typically lost as heat when braking—into electrical energy that can be stored in the battery for later use is known as regenerative braking. It is a productive method of increasing an electric vehicle’s driving range and lessening the strain on its mechanical brakes.

Power Electronics and Traction Motors

Another type of power electronic converter is the Inverter, used to invert high DC voltage, resulting in a variable AC voltage and frequency supply that can be used to feed and power an electric traction motor. Inverter also determines the driving behaviour and electric motor control.

The inverter always operates in the same way, whether the motor is brushless DC, synchronous, or asynchronous. To improve the range, efficiency and performance of the electric motor, modern inverters also include intelligent control algorithms that enable variable frequency drive.

During regenerative braking, the traction motor functions as a generator. The generated AC power must be converted back to DC power for battery charging.

Innovations in the Field of Power Electronics for Electric Vehicles

Manufacturers of electric vehicles are searching for the newest technological advancements to satisfy the expanding market demands. In this section, we explore innovations and trends in the field of power electronics for electric vehicles.

1. Wide Bandgap (WBG) semiconductor devices

The converter’s core relies on power semiconductors.

For EVs to operate safely and effectively, designers must take these conditions into account and include the proper thermal management systems.

3. High-power density converters – Increased power per cubic centimetre

High-power density converters are crucial to the powertrain’s ability to maximize vehicle mobility and reduce power consumption. The passive component size in all power converters is inversely proportional to the switching frequency. The most common method for minimizing the size of passive components and lowering the thruster’s volume and weight is to increase the switching frequency.

The size of passive components and switching losses can be reduced in these converters by using WBG semiconductors and raising the switching frequency. However, when passive component volume is decreased, the surface area available for cooling them is also decreased. This could lead to new challenges in high-power density converters.

4. WBG semiconductor impact on EMI

WBG semiconductor-based inverters’ high switching frequency and quick switching present difficulties for EMI problems in the vehicle and shorten the lifespan and operation of the traction motor. While the problems may be resolved by slowing down WBG devices to the same pace as conventional switching devices, doing so will also result in the loss of the efficiency and power density gains that come with switching to WBG devices.

5. Affordability and cost reduction
