WARNING
General Texas Instruments High Voltage Evaluation (TI HV EVM) User Safety Guidelines
Always follow TI’s setup and application instructions, including use of all interface components within their
recommended electrical rated voltage and power limits. Always use electrical safety precautions to help
ensure your personal safety and those working around you. Contact TI's Product Information Center
http://support/ti./com for further information.
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions may result in personal injury, property damage, or
death due to electrical shock and burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed
printed circuit board assembly. It is intended strictly for use in development laboratory environments,
solely for qualified professional users having training, expertise and knowledge of electrical safety
risks in development and application of high voltage electrical circuits. Any other use and/or
application are strictly prohibited by Texas Instruments. If you are not suitable qualified, you should
immediately stop from further use of the HV EVM.
1. Work Area Safety
1. Keep work area clean and orderly.
2. Qualified observer(s) must be present anytime circuits are energized.
3. Effective barriers and signage must be present in the area where the TI HV EVM and its interface
electronics are energized, indicating operation of accessible high voltages may be present, for the
purpose of protecting inadvertent access.
4. All interface circuits, power supplies, evaluation modules, instruments, meters, scopes and other
related apparatus used in a development environment exceeding 50Vrms/75VDC must be
electrically located within a protected Emergency Power Off EPO protected power strip.
5. Use stable and nonconductive work surface.
6. Use adequately insulated clamps and wires to attach measurement probes and instruments. No
freehand testing whenever possible.
2. Electrical Safety
As a precautionary measure, it is always a good engineering practice to assume that the entire EVM
may have fully accessible and active high voltages.
1. De-energize the TI HV EVM and all its inputs, outputs and electrical loads before performing any
electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely
de-energized.
2. With the EVM confirmed de-energized, proceed with required electrical circuit configurations,
wiring, measurement equipment connection, and other application needs, while still assuming the
EVM circuit and measuring instruments are electrically live.
3. After EVM readiness is complete, energize the EVM as intended.
WARNING: WHILE THE EVM IS ENERGIZED, NEVER TOUCH THE EVM OR ITS ELECTRICAL
CIRCUITS AS THEY COULD BE AT HIGH VOLTAGES CAPABLE OF CAUSING ELECTRICAL
SHOCK HAZARD.
3. Personal Safety
1. Wear personal protective equipment (for example, latex gloves or safety glasses with side shields)
or protect EVM in an adequate lucent plastic box with interlocks to protect from accidental touch.
Limitation for safe use:
EVMs are not to be used as all or part of a production unit.

Test Setup
5.2 Recommended Test Setup at No Load
Figure 2 shows the equipment setup for testing at no load. It is important to note that in this setup, current
drawn by the voltage meter does not flow through the current meter.
Also, do not connect oscilloscope probes or any other sensing devices to the unit while measuring no-load
power, as these can provide a path for common mode current to flow. This causes an error in the
measurements.
During the no-load test, the current meter should be set to long-averaging mode and a few minutes should
be allowed for the reading to be accurate. Additionally, an appropriate current scale factor should be used.

8 Test Procedure
1. Refer to Figure 3 for basic setup. The required equipment for this measurement is listed in Section 5.1.
2. Before making electrical connections, visually check the board to make sure there are no suspected
spots of damage.
3. Keep the DC voltage source output off, connect it to J2 (+) and J3 (-). The DC voltage source should
be isolated and meet the IEC60950 requirement. Set the DC output voltage within the range specified
in Table 1, between 340 VDC and 410 VDC; set the DC source current limit to 1 A.
NOTE: The board has no fuse installed and relies on the external voltage source current limit to
ensure circuit protection.
4. Connect an electronic load set to either constant current mode or constant resistance mode. The load
current range is from 0 A to 10 A.
5. Keep the AC voltage source output off, connect it to J1 with AC_line to J1-1, AC_earth to J1-2,
AC_neutral to J1-3. The AC voltage source should be isolated and meet the IEC60950 requirement.
Set the AC output voltage in the range specified in Table 1, between 85 VAC and 264 VAC; set the AC
source current limit to 200 mA.
6. If the load does not have a current or a power display, a current meter needs to be inserted between
the load and the board.
7. Connect a voltage meter across the load and set the meter’s scale to 20 VDC.
8. Turn on the AC voltage source output.
9. Turn on the DC voltage source output. Then the measurements can be made.
8.1 Equipment Shutdown
1. Shut down AC voltage source.
2. Shut down DC voltage source.
3. Shut down electronic load.
