Who are the other 118 Power Electronics Startups?


According to the Paris Agreement aimed at control over greenhouse gas (GHG) emissions, the amount of GHG from transportation alone amounts to 23% of the total. Governments and public bodies, automotive OEMs and their engineering suppliers framed their strategy towards vehicle electrification in order to reduce GHG. The core components in an Electric Vehicle (EV) comprise a battery, power electronics, a drivetrain, and charging units. The main purpose of this article is to showcase the most promising solutions in the area of power electronics, which accounts for 30% of the total EV cost and is the second most recent and hot EV topic  – after batteries.

Power Electronics & Its Components

Power electronics is responsible for controlling and converting electrical power in the system. Major power electronics components and their functionalities in an EV system are as follows:


Converts Direct Current (DC) from a Li-ion battery source into Alternating Current (AC) that is suitable for the traction electric motor to operate. Swedish startup Ascatron develops Silicon Carbide (SiC) powered semiconductor devices which find its application in EV inverters. The SiC-based inverters theoretically reduce the energy losses by 90%, and less heat is generated during the power transfer at a lower cost due to the smaller size of SiC compared to Si-based devices.

Voltage Converter

Converts DC/AC from one voltage level to another that stores the energy temporarily and releases the energy at a different voltage. There are mainly 2 modes of using such converters in EV such as:

  1. Converter for 48V system – essential for power transfer to a traction motor. The Indian company Altigreen started its journey with a 48V powertrain system for Hybrid Electric Vehicle and made the transition towards a full stack electric vehicle system developer including in-house developed converters.
  2.  Converter for 12V system – essential for power transfer to auxiliary electronic devices. British startup Petalite holds multiple patents and developments in EV supercharging. They currently develop a 6-48V charging system for multiple applications such as hardware integration.

Controller Unit

A controller unit is an inverter and converter combination that recharges the battery pack of an EV during regenerative braking, which develops kinetic energy while braking. The flow of energy to and from the battery is controlled using a controller unit in tandem with the Converter-Inverter combinations. UK-based Pi Innovo provides end-to-end system engineering services to the automotive industry and has come up with a vehicle control module that is adapted to a 24V vehicle application which is able to provide scalability for volume production in a short span of time.

Electric Motors

In place of an IC engine, motors are implemented to convert the electrical energy into mechanical energy for vehicle propulsion. Israeli EVR Motors develops scalable, competitive electric motors that are 50% lighter and 40% cheaper than RFPM motors. They function above 100 kW peak at 48V for typical electric vehicle motion.
