Beschreibung
Air conditioner (A/C) designs need to meet stringent energy efficiency ratings and power factor specifications to reduce overall power consumption. High energy efficiency is achieved by using an inverter-based variable speed drive for the brushless motor-based compressor and condenser fans. The variable speed drive and the sensorless field-oriented control (FOC) of brushless motors allow an appliance to operate at an optimal power setting compared to a fixed speed single phase AC induction motor (ACIM) drive. Power factor correction (PFC) is required for all high-power appliances to connect to the electrical grid. Microchip’s Air Conditioner reference design, based on the dual core dsPIC33CH family of digital signal controllers, demonstrates efficient control of the condenser fan, compressor, PFC and the overall application logic implementation. The high-performance dsPIC33C DSCs (Dual core dsPIC33CH DSCs and Single core dsPIC33CK DSCs) offer the right set of peripherals that is ideal for dual motor control and enables replacing three controllers with one for a cost advantage in your design. This reference design has proven power stages for high power PFC (220V, 1.8 KW), condenser fan (120 W) and compressor (1.34 KW) motor control. Additional features like temperature sensor interfaces, field communications and valve drives will enable you to develop on this platform for a wide variety of air conditioner systems like window A/Cs and the outdoor unit of split A/Cs.
