The teaching unit is suitable for use both inthe laboratory and in a conventional combustion engine vehicle. Such a vehiclewill be supplemented by the main components of a hybrid vehicle, which can thenbe examined in detail
Pilot line with switching relays withintegrated LEDs to illustrate the switching function and system verification
Measurable voltage at the inverterapproximately 210V
Connecting the terminals 30, 31 and 15
Disconnect with original service plug
Signals at the symbolic electric motormeasurable, also filtered in sinusoidal shape, by the smoothing effect of theengine
Signals at the inverter input and outputmeasure, approximately 210V including charging and discharging curves
Inverter generates 3-phase PWM signals, about210V
Signals and messages of the CAN-Buscommunication measurable.
Learning Objectives:
Acquire knowledge about the interaction ofthe electronic components between the high-voltage battery, inverter andelectric motor
Criteria for the use of test devices
Deepen your expertise to optimally adjust oscilloscopes and evaluate the presentations
Represent pulse width modulated signals and sinusoidal wave forms in detail with the oscilloscope, also between individual phases
Recognize the dangers of high-voltage power components, explain accident prevention regulations
Security rules: disconnect, secure against reconnection, ensure that there is no voltage, log the steps.
