Targeting solar-based designs, their 61800 model has been built to solve some of the problems previously faced by designers — for instance, normally the PV inverter from the solar cell has to completely consume the power which results in the engineer having to add resistance that wastes power, but the new model does not require that.
Chroma also featured a programmable DC electronic load (6301A), for the test and evaluation of multi-output AC/DC power supplies, DC/DC converters, chargers and power electronic components. Specifically designed for applications in R&D, production and incoming inspection, the system is configured by plugging the user selectable load modules into the system mainframe. This system has modules with power ratings varying from 20 watts to 1200 watts and can simulate a wide range of loading applications. The programmable parameters include load level, slew rate, duration, and conducting voltage, all of which can be stored on the on-board EEPROM for up to 100 different sets.
Wayne-Kerr Electronics Corp.
Wayne-Kerr is the second of the three winners of the Gold medal for technical innovation and Allen Miller, senior design engineer from Wayne-Kerr was available at the Technology Innovation Awards Pavillion. The winning product is a 120MHz HF DC bias current unit with an accuracy of (+-) 1 per cent, and also permits the analysis of wound components with levels of DC bias current higher than the standard 100mA for high frequency signals in coils. The serial communication bus on this device controls application of DC current and monitors the status of analyser, including warning signals such as excessive voltage drop and over temperature. Additionally, up to 4 units can be paralleled together.
Eris Technology Corporation
Vincent Chiang from Eris began by explaining that the company is mainly into design, manufacturing, and services for diodes and related products such as Schottky wafers, Zener wafers, and multiple rectifiers and diodes.
Eris also brought in two award-winning components to TAITRONICS this year. Joyce Leong, sales engineer at Eric talked about the ultra thin bridge rectifier for LED lighting, and a Shottky diode whose new production technology allowed it to be physically shrunk by 43 per cent.
The first product, which is an ultra think bridge rectifier, is an EBS rectifier with a thickness of a mere 1.2mm. This makes it 53 per cent smaller than MBS and 21 per cent smaller than ABS. The best part is that even with the radically reduced size and surface area, the component is still able to achieve good thermal dissipation.
The second component, which is the radically shrunk Schottky diode, is claimed by Eris to have improved high current behaviour as well as an improved production process. Built with deep P+ diffusion, there is a resistivity reduction of about 25 per cent for this diode, which makes it consumes less power under forward bias. It comes on a wafer and is ideal to be applied to 3C electronics looking at even smaller sizes.
Center Technology Corp
Athena Chang, Vice Manager of sales at Center Technology Corp. explains that they are a manufacturer of hand-held instruments. The company’s focus is on the international market rather than within Taiwan with 95 per cent of their business coming in from abroad.
One of the hand-held products which they are marketing here is the LCR meter. This portable device could be used by field engineers for measuring inductance, capacitance or even as a typical DMM.
Good Will Instrument Co (GW-Instek)
Liao Yu Ju is the Director for the Marketing and Service Department of Good Will Instrument Co, and they are having a grand time here at TAITRONICS with two of the GWInstek branded products winning the 2013 Technology Innovation Awards.
One winner is a dual-channel arbitrary function generator which they claim to be their first basic level model. The product is targeted at being used in helping testing dual-signal applications such as differential or IQ signalling. The user can also edit the 66 built-in waveforms, or even create a whole new one.
The second product is a programmable high-precision DC power supply with a dual range of 15v/3A or 9V/5A. The winning model, PPH-1503, is specially designed to meet low power consumption requirements along with accuracy, speed and resolution in areas like device inspection, R&D labs, or maintenance centers where a high precision power supply with DVM is required.
Additionally, they have a product targeting the education sector now, which is actually a design reuse of an existing instrument- this kit is called the GRF1300.
Starconn
Starconn is one of three companies to have won a gold medal in the Technical Innovation Awards. May Chang, deputy manager of the networking department was available at the venue to represent Starconn and Chief Land Electronic Co. Ltd. Their winning product is a high speed connector on back plane, which provides data rates up to 18Gb/s under differential signal. It also features a special shielding design and close signal pairs, which allow it to perform with lower insertion loss and crosstalk. These connectors are targeted at application areas like telecom, router, server, wifi networking and in data centers.
