Refrigerators
Since refrigerators work continuously, it is important to reduce their power consumption. At the same time, the market demand for ample indoor space is driving the need for thinner heat insulators and smaller motors. Because refrigerators are used in homes, it is necessary to improve motor efficiency, even at low speeds, in order to reduce acoustic noise and vibration. An inverter controls a compressor. Various sensors and a microcontroller work in tandem to regulate indoor temperatures and humidity. The compressor driver consists of IGBTs or power MOSFETs (PWMOSFETs). Power factor correction (PFC) ICs or IGBTs are used in the power supply circuit to keep harmonics in the input current below the IEC limit.
