When it comes to efficiency, it is a very important topic. Efficiency generally refers to the ratio of work output to input. In layman's terms, it is the ratio of achievement to time, effort, and money used when performing a task. Output is greater than input, it is positive efficiency, output is less than input, it is negative efficiency. Increasing work efficiency requires that the positive efficiency value be continuously increased, and the higher the efficiency, the greater the value generated. For the circuit system, work efficiency is extremely important, it can be used to assess the system's capabilities. Especially in the power application circuit, the output is greater than the input, requiring the circuit system to have a very high efficiency conversion rate. Power application circuit status: There are many applications for power switch applications, including all relevant aspects of photovoltaic inverters and HID lamp ballasts and power supplies for telecommunications and servers. Designers of these applications are facing pressure to continuously improve performance, but also need to reduce the board size and ensure reliable operation. Take the example of a photovoltaic cell used in a solar panel. As the development of this market is maturing, the market is increasingly demanding more compact and more efficient electronics, ensuring that every milliwatt of energy obtained from the sun can be used for the load. Inverters are an important part of every solar power system. Photovoltaic inverters convert the direct current generated by a photovoltaic array into alternating current with a local line voltage and frequency, ready to be sent to the grid, or used to supply an off-line grid. We also provide a micro-inverter with only one panel attached to ensure that any panel derating output (perhaps due to cloudy or snowfall) does not result in a disproportionate impact on the overall array output. Inverter designers usually face some seemingly contradictory requirements, such as improving performance and minimizing losses, reducing the size and ensuring reliability. Where are the problems? The basic components of a power switch application circuit are MOSFETs and fast recovery diodes. MOSFETs and recovery diodes are also important for telecommunication and server power supplies with full-bridge or zero-voltage switching/phase-shifting topologies, full-bridge motor control systems, uninterruptible power supplies, and high intensity discharge ballast (HID) lamps. Power MOSFETs are the preferred switching technology for all of these designs because they offer simple drive options for efficient switching at high voltage and high frequency conditions. In most such applications, a nominal value of 600V is usually a sufficient upper range to ensure safe handling of high voltage transients. Obviously, if the efficiency of the MOSFET is not high enough and the loss of the device itself is relatively large, then the efficiency and life of the entire circuit system will not be very high. MOSFET reliability is also a very important consideration for systems that expect the life of a consumer product to exceed the typical lifetime. For example, photovoltaic inverters or industrial motor control systems are expected to last 10, 15 or 20 years (or more). In addition, device requirements may also include maintaining good performance at extreme temperatures (for example, in harsh industrial environments), or maintaining stable output under all climatic conditions. How to solve the problem? Careful selection of the appropriate MOSFET device can provide tremendous advantages in solving all these problems. By minimizing MOSFET losses (substantially divided into conduction losses and switching losses), it helps improve overall efficiency. Using Toshiba DTMOSIV Super Junction MOSFETs to Solve These Problems Toshiba Electronics and Storage Devices Co., Ltd. introduced a high-speed diode based on the fourth-generation 600V system Super Junction MOSFET "DTMOSIV" series. The new series is built using the latest single epitaxial process, and its on-resistance per unit area (RDS(ON)•A) is about 30% lower than that of the existing products, and it is at the leading level in the industry. In addition, the reverse recovery time of high-speed parasitic diodes is approximately one-third that of existing products, reducing MOSFET losses and helping to improve overall circuit efficiency. How to achieve? In the past, power MOSFETs often caused damage to the device due to the reverse current of inductive loads. Because MOSFETs switch at high frequencies, fast recovery diodes (FRDs) are needed, and their characteristics also help improve efficiency. Faster FRD reverse recovery time (trr) helps minimize switching losses. Toshiba's latest fourth-generation super-junction DTMOSIV technology enables it to integrate fast recovery diodes inside the MOSFET package, saving space while maintaining the same package size as previous generation MOSFETs, reducing component count, and helping to simplify Design and streamline inventory. Toshiba's DTMOSIV process is based on deep-slot filling technology, which reduces the number of process steps, lowers costs, and improves the performance of superjunction MOSFETs. This reduces circuit losses and improves overall system efficiency and performance.
