IGBT in Hybrid Electric Vehicles

Nearly 20 years ago, IGBT modules were first commenced to be used mainly in industrial equipment, and are now being utilized in electric power conversion systems for controlling motors in a wide range of fields, ranging from household appliances such as air conditioners to applications in the railroad industry. In recent years, the extent of automotive applications has been expanded and improvement is aiming to realize IGBT modules having even higher levels of performance. A hybrid vehicle system consists of an electric motor, a battery, and an inverter. An electric power conversion system is needed to supply electrical energy from the battery to the motor, and to store energy generated by the motor in the battery. 

The inverter is used as that power conversion system. IGBTs (insulated gate bipolar transistors) are one of the most common modules to use as the main switching device in this electric power conversion system. Hybrid systems can be broadly categorized as either a dual-motor system (traction motor and generation motor) focused on travel performance or a single motor system that combines traction and generation functions and that is focused on miniaturization. The single-motor hybrid system, known as a parallel hybrid system (hereafter referred to as a parallel hybrid), is expected to increase in popularity with application to small vehicles where the parallel hybrid advantages of small size and lightweight can be fully appreciated.

IGBT with Microwave Oven

Microwave ovens are used to heat foods quickly and conveniently and it has become an inseparable part of our kitchens and offices nowadays. It is also used for stewing, frying, baking, steaming, and fermenting foods. Microwave ovens are designed for tabletop use or for mounting above the range. Microwave ovens heat food by following the principle of dielectric heating using microwave radiation, usually at a frequency of 2.45 GHz, through the food. Water, fat, and other substances in the food absorb energy from the microwaves resulting in heating. 

The microwaves interact with the food in a uniform fashion leading to food being more evenly heated throughout. Prior to the availableness of the IGBT, the traditional power supply for the magnetron was a Ferro-resonant circuit. Although simple in construction, this power supply was heavy and bulky because of the large size and weight of the low-frequency (50-60 Hz) step-up transformer. After the availability of the IGBT, a magnetron power supply based upon using a high-frequency inverter was developed. In this new power supply, the anode voltage of the Magnetron rises above 3500 volts when the IGBT is turned on allowing it to generate microwave energy. The power delivered by the magnetron can, therefore, be precisely controlled using the on-time for the IGBT. Using the IGBT-based inverter circuit, the weight of the transformer could be lessened by more than 10-times.

IGBT in Vacuum Cleaners

A vacuum cleaner is an appliance that uses an air pump to create a partial vacuum to suck up dust and dirt from floors and other surfaces. The dirt is collected by a dust-bag for future disposal. Hubert Cecil Booth invented the motorized vacuum cleaner in 1901. Since then, their use has proliferated and vacuum cleaners are now very commonly used in homes on a regular basis to maintain a healthy living environment. Manufacturers of vacuum cleaners include Eureka, Hoover, Bissell, and Dyson. In the past, universal motors were mostly used for vacuum cleaners due to high operating speed at low cost. However, these motors use a mechanical brush that wears out at high speeds limiting the performance. 

Modern vacuum cleaners with higher output power (suction) are designed using switched reluctance motors. The power circuits used for the operation of the switched reluctance motor in vacuum cleaners. These circuits utilize IGBTs to overcome the difficult start-up problem for switched reluctance motors and for maintaining a high operating speed. The author state: “Its lifetime is extended 4 times than that of conventional motor and its suction power is increased 20% at the same volume of conventional universal motor”.

IGBT in Refrigerator Compressors

Refrigerators have become essential appliances in society for the preservation of food and beverages. The quality of life for people has been greatly enhanced with the availability of affordable refrigerators for homes. Most household refrigerators utilize the vapor compression cycle with a circulating refrigerant used to cool the refrigerator compartment. Household refrigerators originally used an on/off controlled, constant-speed, single-phase induction motor to drive the compressor. The poor efficiency of this approach made the refrigerator one of the highest power consumption appliances in the home. In order to improve the efficiency, modern refrigerators with the Energy Star rating utilize variable-speed, three-phase induction motor drives.

 Current models that are Energy Star qualified to use 50 percent less energy than the average models made in 1974. The variable speed drive to the induction motor is provided using the six IGBTs in the inverter stage. The author states: “The total energy savings were about 40%. The system is very quiet and maintains a constant temperature within 0.1 degrees Celsius which improves the quality and shelf life of food stored in the refrigerator.” Many companies have optimized IGBTs for use in refrigerator compressor drives due to the large market opportunity. 

Some companies have developed intelligent power modules, which combine the IGBTs, fly-back rectifiers, and the drive circuits into a single module. This provides a very compact and low-cost motor drive option that can be easily adapted for the manufacturing of refrigerators.
