Infineon Technologies Small Home Appliance Solutions

Infineon Small Home Appliance Solutions features a portfolio of products that fit into small home appliance applications. There is a growing trend for style and more efficiency, which designers are addressing with countless variations. Energy-efficient, modern-looking, wipe-clean, and hermetically sealed surfaces are only a few characteristics that a design engineer has to consider and incorporate into new designs. Infineon delivers solutions for several key areas, such as induction heating, as well as appliances that require motor control solutions with energy-efficient, integrated power devices.

Induction Heating Example

The F Series Protected IGBT with TRENCHSTOP™ RC-H5 technology is ideal for induction heating applications and helps to create compact, highly integrated designs. The device incorporates a current sensing circuitry in conjunction with the existing current sense resistor required in induction heating designs. This limits, cycle by cycle, the resonant energy in the LC tank and the peak turn-on current, as well as limiting the maximum voltage across the IGBT.

An additional active voltage clamp sensed via a voltage sense input ensures the IGBT is not subjected to voltages beyond the specified breakdown voltage. This control mechanism is an improved version of a diode-based active clamp, actively turning on the IGBT to dissipate the surge energy while keeping a constant VCE. The F Series is offered in a TO-247 package to simplify integration into existing designs.

Low Power Motor Control Example

The trend toward more futuristic designs requires electronic solutions with high levels of integration and innovative packaging, especially when it comes to heat dissipation. To meet this challenge, there are various levels of integration for motor control solutions, such as the integration of the gate driver and power stage IGBTs or MOSFETs into a single device.

This is supported with the CIPOS™ Intelligent Power Module (IPM) range of energy-efficient, integrated power devices. At the smallest end of the scale, the CIPOS Nano series provides easy implementation of three-phase or half-bridge motor control, while making use of the PCB copper traces to dissipate heat from the module. This results in cost savings, and in some cases, eliminates the need for a heat sink.

How To Power

The fusion of the control solution and software for variable speed drive of permanent magnet motors: Devices such as the iMOTION™ IMC100 deliver a motor control solution that can be parameterized to control the chosen motor without the complexity of software development. Where space is at an absolute premium, the fully integrated iMOTION IMM100 Series provides everything from the motor control through to the gate drivers and power stage, and is integrated into a tiny 12x12mm PowerQFN package.
