The power devices of the inverter are different for the front and rear, with the front inverter using an IGBT power module and the rear inverter using a SiC (silicon carbide) MOSFET power module. The speed reducer is a standard 3-axis, 2-stage reducer for BEV e-Axles.
The inverter stage is a basic building block for digital logic circuits and memory cells. A generic inverter stage is illustrated below on the left. It consists of two devices,
In order to have a good understanding, let’s first start by looking at the internal structure of an inverter. An inverter is composed of the front part and the rear part. The front part, the “converter circuit” converts AC to DC while the rear part, the “inverter circuit” converts DC to AC.
An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
