Application Areas of the DSI45-16A

Industrial power electronics systems

In industrial inverters, servo drives and other equipment, the DSI45-16A can be used as an output rectifier diode or a continuity diode to handle the energy fed back from the motor. Its high voltage and fast recovery characteristics are especially suitable for PWM inverter applications, which can effectively suppress voltage spikes and protect power switching devices.

Renewable Energy Field

In new energy equipment such as solar inverters and wind power converters, the DSI45-16A can be used in the rectifier and continuity circuits of the DC-AC conversion stage. Its high efficiency helps to improve the overall power generation efficiency of the system, and its wide temperature range is adaptable to harsh outdoor environments.

Power Transmission and Distribution

Used in high-voltage DC-DC converters, uninterruptible power supplies (UPS), and other power equipment, the DSI45-16A can reliably handle high voltages and currents to ensure a stable and efficient power conversion process.

DSI45-16A typical application circuit design recommendations:

Thermal design: Although the DSI45-16A itself has excellent thermal characteristics, it is still necessary to consider appropriate thermal measures, such as the use of heatsinks or forced air-cooling, for high-current applications.

Layout optimisation: When the DSI45-16A is used in high frequency applications, the connection distance between the diode and the relevant power devices should be shortened as much as possible to reduce the influence of parasitic inductance on the switching characteristics.

Protection circuitry: For inductive load applications, it is recommended that the DSI45-16A be equipped with an appropriate snubber circuit (snubber) to suppress voltage spikes and extend device life.

Parallel use: DSI45-16A for large current demand, can be used in parallel with multiple devices, but need to pay attention to the equalisation measures to ensure a balanced distribution of current.
