In order to prevent the formation of high voltage across the switch, a freewheeling diode is just a diode linked across the inductive load terminals.
This diode provides a short circuit path for the flow of inductor decay current and subsequently the waste of stored energy in the inductor when the inductive circuit is switched off. Other names for this diode are Flywheel and Flyback diode.
The primary function of a freewheeling or flyback diode is to provide a short circuit channel in order to free wheel the stored energy in an inductor. This is important to prevent high voltage from building up across the switch contacts and diode in the event of an abrupt decrease in circuit current.
The amount of energy stored in the inductor is (LI2)/2 when switch S is closed because the steady state current I across the circuit equals (V/R). The current will abruptly drop to zero from its stable value of I = (V/R) when this switch S is opened.
A large reverse voltage (according to Lenz's law) equal to L(di/dt) will emerge across the inductor terminals as a result of this abrupt current decay, and subsequently across the diode and switch. Sparks will fly across the switch contacts as a result. A diode may sustain damage if its reverse voltage is higher than its peak inverse voltage.
A freewheeling or flyback diode is put across the inductive load RL to prevent such occurrences.
The Global Free Wheeling Diodes market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024to 2030.
The new Press Pack IGBT (PPI) with inbuilt freewheeling diodes (FWD) in Ceramic Disc Housings from Infineon Technologies Bipolar GmbH & Co. KG adds to the family of high-power Prime Switches.
This PPI is perfect for high current Modular Multilevel Converters (MMC), medium voltage drives, DC breakers, wind turbine converters, and traction systems. It is specifically developed for transmission and distribution applications.
The blocking voltage of the Prime Switch IGBT is 4.5 kV at 3000 A without FWD and 2000 A with FWD. Infineon provides external freewheeling diodes in four different silicon diameters: D1600U45X122, D2700U45X122, D3900U45X172, and D4600U45X172, all of which are compatible with the 3000 A PPI.
Using industry-leading, high-voltage IGBT chip trench technology and highly dependable, field-proven press-pack technology,offers consumers a great, high-performing alternative for applications requiring extremely high power. Additionally, the devices present fresh chances for high-power applications to have cost, loss, and reliability optimized.
