Operating range and performances
The STEVAL-IHT008V1 board is designed to operate inside the following operating ranges:
Line voltage, 2 ranges are possible:
198-264 V RMS, 50 or 60 Hz
90-132 V RMS, 50 or 60 Hz. For this voltage range, operation both in rectifier
mode (DC peak voltage = peak line voltage) or in doubler mode are possible (see
Section 2.2: "Board connection and start-up"
).
Ambient temperature: 0°C to 60°C
Maximum DC load power:
DC load (connected between HVDC and GND-DC): 1000 W or 500 W
respectively for operation on 230 V or 120 V mains.
Maximum AC load power:
T1: maximum load RMS current has to be lower than 1.1 A, this allows 250 VA or
130 VA power for operation on 230 V or 120 V mains, respectively. This Triac
can be used to control a heating resistor or a pump.
T2 to T5: the footprint for each of these devices allow either a SMBflat-3L or a
SOT-223 package to be soldered. By default, two ACS108-8SN (SOT-223) are
used for T2 and T3, with a 5.5 mm² copper area under the tab. These devices
can control an RMS load current up to 0.6 A. This allows a 100 VA or 50 VA
power load to be controlled on 230 V or 120 V mains, respectively. By default,
two Z0109MUF (SMBflat-3L) are used for T4 and T5, with a 33.6 mm² copper
area under the tab. These devices can control an RMS load current up to 0.44 A.
This allows a 140 VA or 70 VA power load to be controlled on 230 V or 120 V
mains, respectively. These four Triacs can be used to control a pump, a fan or
any electromagnet (valve, damper, door-lock, etc.).
Allowed DC output capacitor (or DC bus capacitor) range: 50 µF to 500 µF (in rectifier
mode) or to 1000 µF (in doubler mode).
This DC output capacitor value is the equivalent value of all capacitors placed in
parallel at the bridge output, like C1, C9, C3, and CPFC at PFC output (refer to
Figure 3: "Connection of a PFC at the HVDC output"
). If an interleaved PFC is
used, all the output capacitors of each PFC must be added.
If the J7 connector is closed (doubler mode), no PFC should be used. C3 is also
not added. In this case, the equivalent capacitor is only C1 (or C9 as they both
have the same value).
