The most important limiting feature of electric vehicles is the amount of energy they can accumulate in their batteries and how long it takes to recharge the empty batteries consumed on the road. When they arrive at a charging station.
Rectifiers, which convert the energy in the city grid into direct current to store in accumulators, must charge the batteries very quickly to meet this new need.
Fast charging requires high voltage. To safely produce these voltages of up to 1000 Volts. This requires the use of advanced components in the electronic circuits that make up the rectifiers. The technical specifications of all the components, from semiconductors to passive components such as capacitors and resistors, need to be reviewed and sized. Cooling such high energy rectifiers poses a problem.
It is necessary to resort to difficult solutions such as circulating water or similar liquids in coolers. However, the entire industry knows that rectifiers are one of the most important bottlenecks for EVs to move from being a fashion product, to widely replacing today's fossil fuel-powered cars.
