Microwave Ovens
The key component of a microwave oven is the microwave generator, also called a magnetron, which is based on a high-frequency resonant power converter that drives a transformer followed by a voltage multiplier bridge to generate the high voltage (several kilovolts) required to drive the magnetron.
ST offers a range of trench-gate field-stop IGBTs and gate drivers that together with high-performance STM32 microcontrollers are ideal for the design of high-efficiency microwave generators. We also supply triacs and AC switches to drive the lamp and the motors for the turntable and fan, as well as a set of environmental sensors and LED and LCD display drivers, touchscreen controllers and proximity sensors for touch-less user interfaces.
