Do Electric Car Inverters use the same Technology as the Inverters used in Photovoltaic Systems? - PowMr


Yes, the inverters in electric vehicles use the same technology as the inverters used in photovoltaic systems. The same basic technology - they both use transistors and pulse width modulation (PWM) technology.

The inverter may be a little different due to different application scenarios (voltage, equipment, control, filtering)
Electric vehicle inverters are three-phase. Solar inverters (small-scale) are single-phase. Small home solar inverters produce 220 or 110 VAC at 60 Hz.

Three-phase inverters simplify the whole system and will make the motor run smoother and draw a smooth current from the battery.
Single-phase inverters are generally used in houses, where single-phase is cheaper than three-phase inverters, but of course, large utility or municipal solar inverters are three-phase. Whether they are three-phase or single-phase inverters, they all have the same basic technology, such as switch-mode power conversion.

EV inverters produce variable frequency and variable power depending on the motor power and speed needed, depending on the vehicle, and of course, using a relatively stable high voltage battery power supply. The PWM frequency (number of pulses per second) of EV and solar inverters is typically between 2kHz and ~20kHz, depending on the application and the switching transistors used.

Solar, energy storage and EV inverters: different categories

If you buy solar, energy storage and electric vehicle inverters at the PowMr store, we'll give you the best service and help you with any questions you may have!

The most fundamental difference between solar, energy storage and electric vehicle inverters: the task of driving the motor. The task of a solar inverter is to drive a component of the grid, so it needs filters to ensure that the current is clean.

The PowMr team has fundamentally different designs of drive motors depending on the task of the drive motor. An electric car has six or more switches, hundreds of amps of input current, and a relatively simple controller. A solar inverter is more complex, even though there are fewer IGBTs and lower current inputs; it requires boosters and filters, which can change the underlying design.
