Automotive Power Testing Solutions

Automotive Power Testing Solutions Predict and analyze power consumption in your automotive applications Automotive electronics operate in one of the harshest environments, countering constant mechanical vibration, noise, and wide temperature ranges, from subzero to > 1,600 ºF, or 800 ºC, temperatures. What’s more challenging is the electrical environment. Carmakers are adding high-speed and high-power electronics to enable advanced driverassistance systems, infotainment, connectivity for vehicle-to-everything (V2X) applications, and, of course, longer-range EVs. This brochure looks at the...

Validating Power at the Device Level The term automotive power device describes diodes, insulatedgate bipolar transistors (IGBTs), MOSFETs, and the newer silicon carbide (SiC) and gallium nitride (GaN) devices. These devices control and convert electric power for various automotive applications, such as body electronics, infotainment and telematics, safety and security, chassis, and, increasingly, powertrains in electric vehicles (EVs). Using devices with low conduction loss and low switching loss is essential to create fuel- and energy-efficient systems. The higher converter / inverter...

CX3300A device current waveform analyzer and anomalous waveform analytics Critical EV functions use numerous microcontroller units (MCUs) and field-programmable gate array (FPGA) units. Any malfunction could lead to potential fatalities and detrimental business impacts, such as mass product recalls. The Keysight CX3300A device current waveform analyzer and anomalous waveform analytics software (Figure 1) rapidly detect and analyze anomalous signals in these MCUs and FPGAs, enabling fast rectification of hardware, firmware, and software defects. The CX3300A includes the following features: •...

Keysight oscilloscopes and pulse generators Switching characteristics are an important part of component-level testing, and Keysight has oscilloscopes and pulse generators that can help evaluate these parameters (see Figure 6). Keysight’s InfiniiVision 4000-X Series oscilloscopes provide sufficient bandwidth and resolution at a reasonable cost, and you can use them with a current probe if necessary. The Keysight 81110A pulse generator provides voltage pulses fast and large enough to characterize automotive components. = Current probe +VDD Figure 6. Evaluating switching characteristics with...

MEMS evaluation using the E4980A LCR meter Measured data deviation 3.0E-15 MEMS capacitive sensors (such as pressure sensors or accelerometers) detect mechanical displacement through capacitance change. Functionality tests of these devices usually use electrostatic force (rather than physical stimulus), as it results in greater test efficiency. However, since the capacitive change in the actuator is tiny, test equipment with the ability to measure capacitance with sub-femtofarad resolution is necessary. The E4980A inductance (L), capacitance (C), and resistance (R) meter is an ideal tool...

Electronic control units (ECUs) for automotive applications need to be immune to the harsh power systems in which they operate. Power system surges and dropouts are common, so the ECU designer needs tools that can replicate and analyze the power transients seen in automotive applications. The designer also needs powerful tools that can replicate waveforms at different power, voltage, and current ratings to analyze and debug designs and ensure that the devices under test (DUTs) conform to ISO 7637-2 and ISO 16750-2 test specifications. ISO 7637-2 “specifies test methods and procedures to...

N3300 Series electronic load Testing multiple-output DC power supplies and DC-DC converters can be time-consuming if you must test each output sequentially. Sequential testing happens when making measurements through a MUX using one digital multimeter (DMM). Using the built-in measurement capabilities of the Keysight N3300A electronic load (Figure 9), you can measure all outputs simultaneously. Alternatively, you can test multiple single-output power sources simultaneously. It also does the following: • processes commands more than 10 times faster than previous electronic loads • simulates...
