iDealTek - Electronics was founded in May 2015 by a team composed of sales and technical personnel. Before founding iDealTek - Electronics, the team members worked in a company called "SHEKONIC" and were engaged in design, production and market operation of various customized power supplies for 9 years. During this period, the team members accumulated rich experience in various power supplies topology design by engaging in developing and manufacturing of thyristor-based SCR power supplies; transistor-based & triode-based linear power supplies, and transistor-based switching power supplies.
During this period with SHEKONIC, the company's power products seemed to be the mainstream products in the market, but with the increase in sales, the company's internal management redundancy and bureaucracy led to the stagnation of technological innovation. In the last 5 years of SHEKONIC (after 2009), with the gradual use of switching magnetic components like IGBTs and MOSFETs in the Chinese market, there had been a trend of high-frequency switching power supplies gradually replacing traditional thyristor-based topological SCR power supplies in high power power supplies market. Through the research on the switching power supply products on the market, we found that the PWM circuit topology of the magnetic components used in the switching power supply combined with the high-frequency transformer can greatly reduce the size and weight of the power supply on the basis of achieving the same output power, and the fast dynamic response feature of switching topology and the more efficient AC/DC conversion give the switching power supplies a faster response speed and higher efficiency. But the disadvantage was also obvious, because the loop matching the switching magnetic components is not completely stable at that time, the occasional loop failure will cause damages to the power supply, which gives people an impression that the reliability of the high-frequency switching power supplies is not as good as the thyristor-based SCR power supplies.
Nevertheless, the team members were still attracted by the superiority of high-frequency switching power supplies topology. From a technical point of view, they believed that high-power switching power supplies using switching PWM technology would become a major trend in the future. Therefore, in the period from 2009 to 2014, they promoted the innovation on the basis of the original power supply topology and launched an improved switching power supply (within 10KW) with hard-switching conversion technology. However, as the power increased, the problem began to appear continuously, the instability of the power supply caused SHEKONIC to have an aversion to the switching power supplies and finally abandon the development plan, which also led to the final departure of the team.
