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.

5 Test Setup

5.1 Test Equipment

DC Voltage Source: capable of 340 VDC to 410 VDC, adjustable, with minimum power rating 200 W, or

current rating not less than 1 A, with current limit function. The DC voltage source to be used should meet

IEC60950 reinforced insulation requirement.

AC Voltage Source: capable of single-phase output AC voltage 85 VAC to 264 VAC, 47 Hz to 63 Hz,

adjustable with minimum power rating 100 W. The AC voltage source to be used should meet IEC60950

reinforced insulation requirement.

DC Digital Multimeter: One unit capable of 0-VDC to 450-VDC input range, four digit display preferred;

and one unit capable of 0-VDC to 20-VDC input range, four digit display preferred.

Output Load: DC load capable of receiving 0 VDC to 20 VDC, 0 A to 15 A, and 0 W to 200 W or greater,

with the capability to display things such as load current and load power.

Current Meter: DC, optional in case the load has no display, one unit, capable of 0 A to 15 A. If you want

to measure standby power, the current meter needs to have a time averaging function.

Oscilloscope: capable of 500-MHz full bandwidth, digital or analog, if digital, 5 Gs/s or better.

Fan: 200-LFM to 400-LFM forced air cooling is recommended, but not required.

Recommended Wire Gauge: capable of 15 A, or better than #14 AWG, with the total length of wire less

than 8 feet (4 feet input and 4 feet return).

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.
