QC3.0 & Type C Technology

Highfive Electronics offers a broad range of “power-supply enabled/specific” solutions and supporting power devices. While Traditional power supply designs use analog ICs with fixed functionality to provide regulated power, the Intelligent Power Supply integrates Digital Signal Controller (DSC) for a fully programmable and flexible solution. Using digital control to implement power conversion functions, developers can realize many benefits for their design and business. These are enabled by the ability to perform the power conversion control via reprogrammable software and the performance and features of our PIC MCU and dsPIC DSC solutions. Below are some examples of Intelligent Power Supply functions:

Lowers System Component Count


  • Valuable board space can be made available for magnetics and power components
  • Power supply control, regulation and protection functions can be incorporated into the same device
  • Auxiliary functions, such as fan control and data logging, are easily integrated

Allows Configurationfor Different Applications


  • Power supply becomes a platform solution for many different applications
  • Can easily be reprogrammed
  • Supports different output voltage levels, operating limits and control inputs
  • Reduces inventory overhead and the support required for multiple platforms

Increases System Efficiency


  • Can adapt to load changes to maximize efficiency by changing power supply switching frequency and control loop configuration
  • Monitor internal temperatures and enable cooling fans only when needed
  • Dynamically change control loop behavior for optimal system response

 

The development of the mobile Internet needs the support of mobile power sources. In this field, there are mainly thin film battery technology, piezoelectric material technology, and wireless charging technology.

In the era of mobile Internet, a very important part of the use of the client is its use time. No matter how excellent the performance is, mobile phones, tablets or other smart products that cannot be turned on when disconnected from a wired power supply cannot be effectively used.

In the need to improve the battery life, a method that can reduce the power consumption at the same time, such as the iPad, saves all the power consumption methods that can be saved, and saves all the space that can be saved, but this is for the rapid development of IT products In terms of it is really uncomfortable. Another way is to improve the efficiency of the battery to provide products with more continuous battery life. The development of mobile Internet needs the support of mobile power. In this field, there are mainly thin film battery technology, piezoelectric material technology, and wireless charging technology.

thin film battery

The most ideal energy source that can be accessed anytime and anywhere is solar energy. The application of solar energy is a problem that mankind has been striving for since history. Although monocrystalline silicon solar cells dominate in large-scale applications and industrial production at this stage, they also expose many shortcomings. The most important problem is the high cost. At the same time, affected by the price of monocrystalline silicon materials and the manufacturing process of monocrystalline silicon cells, it is very difficult to significantly reduce the cost of monocrystalline silicon solar cells.

thus produced its alternative thin film solar cells, including amorphous silicon thin film solar cells, indium copper selenide and cadmium telluride thin film cells, and polycrystalline silicon thin film solar cells. The most important advantages of amorphous silicon thin-film solar cells are their low cost and easy preparation. Because their photoelectric conversion efficiency will decay with the continuation of the illumination time, its instability is also obvious.

As for the efficiency of polycrystalline silicon thin film batteries of copper-indium selenide and cadmium telluride is higher than that of amorphous silicon thin-film batteries, the cost is lower than that of monocrystalline silicon batteries, and it is easy to mass-produce, and there is no problem of sharp reduction in efficiency. A better alternative. It’s just that the large amount of pollution produced during the production of polycrystalline silicon thin-film batteries cannot be ignored. The raw materials selenium, indium, and tellurium are all rarer metals, and there is little room for further cost reduction.

Polycrystalline silicon thin-film batteries use far less silicon than monocrystalline silicon, and there is no sharp drop in efficiency. They may be prepared on cheap substrates. The cost is expected to be much lower than that of monocrystalline silicon batteries. The laboratory efficiency has reached 18%, much higher than the efficiency of amorphous silicon thin film batteries. Therefore, polycrystalline silicon thin film batteries are considered to be the next generation solar cells that are most likely to replace monocrystalline silicon cells and amorphous silicon thin film batteries, and have now become a research hotspot in the international solar field.

The production cost of thin-film solar cells is relatively low, and its market share has continued to grow in recent years. At present, the highest photoelectric conversion rate is the copper indium gallium selenium solar cell, which can reach 20%, but it is still far from the theoretical value of more than 30%. The main problem is that the distribution and proportion of indium and gallium in the material cannot reach the ideal value. .
