Description

LT3752-1/LT8311

200W Active Clamp Forward

Converter with Input Voltage 150V to 400V

Demonstration circuit 1929A is a 200W active clamp for-

ward converter featuring the LT

3752-1/LT8311 chipset.

It operates at about 100kHz and produces a regulated 12V

output from an input voltage ranging from 150V to 400V,

making it well suited for automotive, industrial, and other

applications. Table 1 summarizes the performance of the

demo board.

The LT3752-1 is a current mode PWM controller opti-

mized for a forward converter with high-side active clamp

transformerreset.Anaccurate,programmablevolt-second

clamp allows primary switch duty cycles above 50% for

better utilization of switch, transformer and rectifier. The

AOUT control signal can be used to power a gate drive

transformer, level-shift driver, or opto-coupler driver

for the high-side N-channel FET. The SOUT controls the

secondary side synchronous rectification. The integrated

housekeeping flyback controller brings great convenience

for both primary and secondary bias circuits. During its

soft-start and soft-stop, LT3752-1 folds back switching

FOR PROPER COMPONENT REPLACEMENT AND

CIRCUIT MODIFICATION.

Demonstration circuit 1929A must be set up as follows

to evaluate the performance of the LT3752-1/LT8311.

Refer to Figure 1 for proper equipment setup and follow

the procedure below.

NOTE. Do not operate DC1929A unless you have the ap-

propriate safety precautions in place on your bench to

guarantee safety. Always remove power before touching,

servicing, or attaching probes to the demo board. Never

leave the DC1929A unattended when under power.

1. With power off, connect the input power supply to the

board. The power supply should be adjustable over

100V ~ 450V range, and at least 3A current capability.

An ammeter capable of measuring 3ADC can be put in

series with the input supply to measure the input cur-

rent. Connect the load to the terminals VOUT+(J1) and

VOUT–(J2) on the board. The load should be adjustable

up to 20A. If efﬁciency measurements are desired, an

ammeter capable of measuring 20ADC or a resistor

shunt can be put in series with the load to measure the

output current. A voltmeter can be placed across the

output terminals (E4, E5) in order to get an accurate

output voltage measurement.

2. Direct airﬂow of 300LFM across the demo circuit for

sustained operation at full load. Refer to Figure 1 for

proper airﬂow direction.

3. Turn on the power at the input. Increase VIN slowly to

150V.

NOTE. Make sure that the input voltage does not exceed

400V. Make sure the load current does not exceed the

specifications.

NOTE. Check the standby current without any load applied

and it should be less or around 25mA at 150V input, or

20mAat400Vinput.Anycross-conductionoftheprimary-

secondary switches will significantly increase the standby

current.

4. Checkfortheproperoutputvoltages.Theoutputshould

be regulated at 12.0V (±2%).

NOTE. If there is no output, temporarily disconnect the

load to make sure that the load is not set too high.

NOTE. By removing the resistor R2, and applying the VIN

between VBand –VIN, the main power circuit is discon-

nected from the control/bias circuits, and the control/bias

circuit can be debugged separately. The standby current

of the control/bias circuit should be less than 2mA.

NOTE. By removing R37 and R40, and adjusting R25 to

107k, the feedback loop is disabled, and the circuit runs

in no-opto bus converter mode.

5. Once the proper output voltage is established, adjust

the input voltage and load current within the operating

range and observe the output voltage regulation, ripple

voltage, efﬁciency and other parameters.

NOTE. When measuring the output voltage ripples, care

must be taken to avoid a long ground lead on the oscillo-

scopeprobe.SeeFigure2forproperscopeprobetechnique.

NOTE. Airflow should be directed to the demo circuit ac-

cording to the direction shown in Figure 1. Running the

circuitatfullload without airflowcouldoverheatthepower

components, and lead to damage of the board. Overload

operationofthedemocircuitisfeasibleforshort-termonly.

Long term overcurrent operation is not recommended,

unless enhanced cooling methods are used.

6. Turn off the load at the output, the power at the input,

and then turn off the airﬂow.
