Electric Vehicle (EV) Controls
SEDEMAC has been developing a suite of products for OEMs participating in the EV story. SEDEMAC provides complete control and power electronics solution-set for 48V electric vehicle (EV) and hybrid electric vehicle (HEV) systems. The portfolio includes motor controllers, battery management systems, and DC/DC converters.
SEDEMAC’s sensorless motor controls offering, Weber, is a product-series of Field Oriented Control (FOC) enabled BLDC motor controllers. These controllers operate two control loops; the inner control loop controlling machine currents for optimal torque generation, and the outer control loop controlling torque reference and field weakening logic. Weber also has a regenerative braking logic for energy efficient operation of the vehicle.
Weber comes in two variants – Weber-S; is suitable for lower power (~2 kW) applications, while Weber-D; is designed for mid power (~10 kW) applications.
