The higher efficiency in the totem pole boost helps to increase the power density. Using a CR instead of relay to limit the inrush current increases the reliability and is particularly suitable in automotive applications, where it is recommended to avoid moving parts. A standard boost has the disadvantage that two diodes of the rectifier bridge are always in series and these as an impact on the efficiency. The tometople architecture gives instead better efficiency, but has a more complex input voltage sensing and requires MOSFETs with almost no reverse recovery charge of the body diode, so CIG MOSFETs. In a simple boost, you have three junctions in series, two bridge diodes and one other element, tudi v postah, če boš delaj. Kaj pa v toten pol je doga unjela, če boš delaj in če boš delaj.

Although in general SCRs have higher voltage drop than standard diodes, this difference is negligible at high currents. We can see in the example here that the difference is minimal, just 20 millivolt, a denominal current of this application, 16A, and in worst case of 150 degrees. Therefore, the usage of SCRs in such high power applications does not impact significantly on the efficiency. Estimike electronics 3.6 kW totem pole PFC achieves very high efficiency, extremely low THD, and digital tuning of peak in rush current. Main to work with both US and European input voltage range, this board provides a 400V output, working with a maximum input current of 60A RMS. It achieves a peak efficiency of 97.7% with a THD of 4.7%. It has been tested up to 45 degrees and is compliant to the main standards. The main semiconductor products inside are two 656 MOSFETs, two isolated drivers, two 1200V SCRs, an STM32 microcontroller, and the Viper 26 for the auxiliary power supply. At startup, the SCR gate signals enable the SCRs just during some pulses, in order to limit the AC in rush current. The algorithm sweeps the triggering angle backward from 180 degrees to zero degrees. SICK MOSFETs operate in safe synchronous conduction mode. As it can be seen from the oscilloscope waveform capture, after MOSFET S1 is turned off, there is a dead time of 200 nanoseconds before MOSFET S2 is turned on. Efficiency is very high at all loading conditions. Higher than 95% already at 500W, that is 15% of the maximum load. THD is below 10% starting from 25% of the maximum load. The microcontroller implements digitally the load feed forward, which improves the load regulation and the load transient response. The picture shows the recovery of the output voltage after 0 to 100% and 100% to zero load steps. The board is equipped with an over-temperature protection mounted on the heat sink. The pictures show the temperature reached by the SICK MOSFETs and the SCRs at maximum load when the fan is on. 83 degrees for the SICK MOSFETs and 71 degrees for the SCRs. In both cases, well below the maximum junction temperature of the components. ST SICK MOSFETs can work up to 200 degrees and ST SCRs up to 150 degrees, ensuring high reliability and the possibility to reduce the heat sink. ST SCR TIRISTOR portfolio include a wide range of products to work from low to very high power, to handle high temperature applications and with high performance characteristics. ST 1200V TIRISTORs are born to work in harsh industrial applications, like motor drives, UPS, charging stations, renewable and also in automotive applications. There is indeed a good number of products with automotive grade qualification. There are several package options available, like this square pack, TO220, TO247, TO247 with long leads, top 3 insulated and new ASPAC Smith. ST Second Generation 650V SICK MOSFETs are widely used in all kind of power conversion and in motor drives. They are available in two sizes, with RDS zone of 0.55 ohm or 20mm ohm in several packages and in industrial and automotive grade. ST isolated gate drivers are available in single channel and in dual channel versions. Both parts are 1700V rated and have for ampere SICK and SOURCE current capability. There are two options of STGAP 2S, the single channel gate driver. One with separated outputs to turn on and off the external MOSFET and one with Miller clamp to avoid induced turn on.
