Description
The STEVAL-IHM029V1 is a low-cost universal
motor control demonstration board designed for
the home appliance market, with particular focus
on vacuum cleaners, food processors and power
tools.
This system features the 20-pin, 8-bit
STM8S103F2 microcontroller running at 16 MHz
(RC user-trimmable internal RC clock), featuring
4 KB of Flash memory, a 10-bit A/D converter,
8/16 bit timers, communication interfaces and 640
bytes E²PROM.
STEVAL-IHM029V1
The power supply circuitry is based on the
VIPer16L, an off-line converter with an 800 V
avalanche-rugged power section, operating at 60
kHz.
The STEVAL-IHM029V1 can control any universal
motor up to 2000 W, thanks to the T1235H, a 12 A
600 V high temperature Triac. The motor control
is based on phase-angle.
In order to limit the in-rush current and possible
current peaks, the demonstration board features a
soft-start routine and a smooth power change
function.
The board passed the pre-compliance tests for
EMC directives IEC 61000-4-4 (burst up to 8 kV)
and IEC 61000-4-5 (surge up to 2 kV).
In standby mode, the STEVAL-IHM029V1 has an
overall standby power consumption below 300
mW.
