IGBT module from Hitachi. The new IGBT module makes high energy efficiency and silent operation of inverters possible. It has High thermal fatigue durability. It is a High speed and low loss IGBT module.
Single plate induction cooker demonstration board Uses ST7LITE09 and STGW40NC60WD (40 A, W series).
The design is entirely controlled by a simple ST7FLITE09Y0 8-bit microcontroller, which provides the PWM driving signals, communicates information to the user interface, and drives the fan and relay control to the plate feedback.
Wilhelm Westermann in Unna/Westphalia in 1948 created and established
WIMA Germany. They make High Technology, Specialized Passive
Components. These are Plastic film capacitors, Paper capacitors and
The capacitors that need special mention are RFI and Snubber
Capacitors. They also make Intermediate Circuit Capacitors or DC-Link
capacitors, that can replace Electrolytics in SMPS or DC/AC Drives.
These capacitors are especially designed to attenuate voltage spikes
on GTO (Gate-Turn-Off) Thyristors and IGBT (Insulated Gate Bipolar
Transistor). They are manufactured in dry-type technology with a
dielectric of metalized polypropylene film and encapsulated in a
cylindrical plastic case sealed with self-extinguishing polyurethane
These caps have Very low self-inductance and High pulse reliability
(snubber). High rms current carrying capability (HF filter). Value
Ratings upto 100uF and 1KV available.
GTO Capacitors - WIMA
The Double Layer Capacitors developed by WIMA are storage capacitors
with highest capacitance values in the Farad range. They are among
others suited to serve as batteries, can deliver considerably higher
currents for a short time, however, and are maintenance free.
SuperCapacitors - WIMA
Despite the limitations of its maximum operating voltage of 2.5 V,
several cells can be built up to enormous capacitance of the desired
voltage by means of series or parallel connection (cascade). When
cascading SuperCaps, the voltage of single cells must not exceed 2.5 V
(decomposition of the electrolyte!)
Hy-Cap single cell model is divided into two categories: EDLC(Electric
Double Layer Capacitor), featuringa higher power, and Hybrid
Capacitor,featuring a higher energy density.
Hy-Cap is an energy storage device that stores instantly a large volume
of electric energy and supplies instantly or continuously higher
current, by the mechanism of absorbing and de-absorbing electric charge.
VINATech is the only producer in the world of catalyst support and
catalysts for fuel cells and MEA (Membrane Electrode Assembly).All of
these products are based on the company's patented CNF materials
