3 Phase Power Inverter Systems for Hybrid and Electric Vehicles (4-Part Series)Four (4) 1-hour online training sessions:
The Power Inverter is the central point of High Voltage distribution in most hybrid systems, whether the vehicle is a Toyota Prius or a Chevrolet Volt. It not only produces Alternating Current (AC) for the motor-generator systems but, it also produces Direct Current (DC) for charging the battery pack, electric air conditioning, and the DC-DC converter system. This series will concentrate on how the Power Inverter System creates AC and DC High Voltage electric power by using the IGBT (power transistor), and software controls. Analysis and Diagnostic strategies will also be covered in this series. Some Scan Tool and off-board diagnostic tools will be discussed in this course. 3-Phase Power Inverter Systems will concentrate on how the Power Inverter System creates AC and DC High Voltage electric power and how electrical current is regulated by control software. Analysis of 3-Phase waveforms and current regulation will be a key metric in this course. Additional diagnostic information about rotor bearings will be introduced. Analysis and Diagnostic strategies and tools will be covered as the main points in this series. At the conclusion of this series the technician will know the fundamentals and operation of Power Inverters and the diagnostic principles of the Power Inverters system. Scan Tool, Scope, Current Probes, and off-board diagnostic tools will be used heavily in this series. This class results in a certificate of completion that will be provided to the participant after successfully completing all online training sessions in the series. The certificate and its stated hours are eligible for NATEF annual credit and may count toward other professional development requirements.

3 PHASE REGENERATIVE BRAKING SYSTEMS (3-PART SERIES)
|
3 Phase Regenerative Braking Systems (3-Part Series)Three (3) 1-hour online training sessions:
Regenerative (Regen) Braking Systems are responsible for capturing vehicle energy normally lost in friction heat and transferring it to the battery pack for storage so it can be used for accelerating the vehicle. It is vital for technicians to understand this system and how it effects hybrid vehicle operation and the driving range of an all-electric vehicle and how the frequency of brake system service is effected. This series will cover how the Friction and Electric Braking systems operating modes and blended to provide a seamless braking experience for the vehicle operator. Special servicing processes for brake bleeding are also used in and need to be understood by the technician. At the conclusion of this series, technicians will know brake system hardware operation and controls, and electric braking operation and controls used in Regen braking. Scan Tool usage, PIDs and DTCs are included in the series for practical application. This class results in a certificate of completion that will be provided to the participant after successfully completing all online training sessions in the series.
