600A / 1200V car drive based on EconoDUAL 3

Infineon's EconoDUAL 3 module is a 600A / 1200V IGBT. The main typical applications include frequency converters for automatic drive systems, central inverters for photovoltaic voltage systems, and automotive diesel engine drivers (CAV). 30%. This article introduces the main features of the EconoDUAL 3 module, typical application circuits and main features of the EconoDUAL â„¢ 3 module driver board, evaluation board circuit, and various IGBT driver circuits and driver board bill of materials (BOM).

The new EconoDUAL 3 module with the designaTIon FF600R12ME4 is at present the most powerful product in the popular EconoDUAL family, offering 600A in 1200V. Typical applicaTIons are frequency converters in automaTIon drive systems, central inverters in photovoltaic systems, and diesel generator drives in vehicles ( CAV). The opTImised module design with regard to interconnection technology and thermal resistance, results in high current utilisation and thus high efficiency. With the EconoDUAL 3 FF600R12ME4, the user can increase the power range by up to 30%, while the package dimensions remain the same. In addition to the familiar soldered version of the control contacts, the highly reliable PressFIT contact technology has been introduced in the EconoDUAL 3 family.

The FF600R12ME4 is the new flagship product of Infineon's well established EconoDUAL â„¢ series. It was developed with a clear focus on full current and power utilization within the inverter design. Hence, the ampacity of the package was increased by ~ 50% and the thermal resistivity R thJC was reduced by ~ 25%, compared to state-of-the-art assembly technologies.

Based on the previous considerations, the development of a new EconoDUAL â„¢ 3 module has been started. The development target was not only to achieve a nominal current rating of 600A in the 1200V blocking voltage class by the implementation of the latest IGBT 4th generation dies, but also to provide a real increase of the achievable RMS output current of the inverter, compared to the already existing 450A EconoDUAL â„¢ 3.

EconoDUAL â„¢ 3 and EconoPACK â„¢ + module driver boards

Evaluation Driver Board for EconoDUAL â„¢ 3 and EconoPACK â„¢ + modules

The Evaluation Driver Board 2ED100E12-F2 for EconoDUAL â„¢ 3 modules as can be seen in Figure 1 and the Evaluation Driver Board 6ED100E12-F2 for EconoPACK â„¢ + modules, shown in Figure 2, were developed to support customers during their first steps designing applications with these modules. The basic version of each board is available from Infineon in small quantities. The properties of these parts are described in the chapter 2.2 of this document whereas the remaining paragraphs provide information intended to enable the customer to copy, modify and qualify the design for production, according to his specific requirements.

The design of the 2ED100E12-F2 and the 6ED100E12-F2 was performed with respect to the environmental conditions described as design target in this document. The requirements for leadfree reflow soldering have been considered when components were selected. The design was tested as described in this documentation but not qualified regarding manufacturing and operation in the whole operating ambient temperature range or lifetime.

Due to their purpose Evaluation Boards are not subjected to the same procedures regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular products.

Main features of EconoDUAL â„¢ 3 module driver board:

The 2ED100E12-F2 and the 6ED100E12-F2 Evaluation Driver Board offers the following features:

Dual channel IGBT driver in 2ED100E12-F2 version, adapted for use with IGBT4

Six channel IGBT driver in 6ED100E12-F2 version

Electrically and mechanically suitable for 600 V and 1200 V EconoDUAL â„¢ 3 or EconoPACK â„¢ + IGBT modules

Includes DC / DC power supply with short circuit protection

Isolated temperature measurement

Short circuit protection with toff <6 μs

Under Voltage Lockout of IGBT driver IC

Positive logic with 5 V CMOS level for PWM and Fault signals

One fault output signal for each leg

PCB is designed to fulfil the requirements of IEC61800-5-1, pollution degree 2, overvoltage category III

The 2ED100E12-F2 and the 6ED100E12-F2 have an integrated DC / DC converter for each leg, which generates the required secondary isolated unsymmetrical supply voltage of +16 V / -8 V. Top and Bottom driver voltages are independently generated by using one unipolar input voltage of 15 V. Additionally, the power supply is protected against gate – emitter short circuit of the IGBTs. In case of DC / DC converter overload, the output voltage drops. This Under Voltage Detection function insures gate voltages within specified range. The fault is reported to the driver's primary side.

Drum type Rice Cooker

 

Features

This type rice cooker is famous with drum type appearance, which is easy operation and easy clean.

There are two type of inner pot ,  one type called white pot which is without non-stick but cheaper price .another one called non-stick pot is polished with emery, Also there are two type non-stick with different price ,it`s depending on different demands to use.

 

And the inner pot cannot be burned on the stove, which will make the pot transfigured and bad contact with the heating plate. While cooking , the heating plate or the fuse is most likely to be burned for the bad contact of the inner pot and the heating plate, Besides, make sure to dry the pot before putting into the outer shell of the rice cooker ,or else the drops of water flowing on the heating plate, will make the heating plate rusted.

 

Applications

Many peoples are used drum type rice cooker for congee and soup, some of peoples are prefer to use this type rice cooker for steaming.
