Air Conditioner Reference Design

**For development reference only, not a product for sale**

Part Number: aircon-board

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.

    • Master core implements Interleaved Boost PFC, system functions and other custom features 
  • 3-phase motor control power stage for driving Low Power High Voltage BLDC/ PMSM motors
The Digital Compensator Design Tool (DCDT) helps power supply designers by simplifying the overall process of determining the digital compensator coefficients and analyzing the control system performance. The DCDT incorporates all feedback gains and delays to provide the most accurate model of the control system. Along with analyzing the closed loop performance via Bode Plots, the user can verify stability by using the DCDT’s root locus and Nyquist plots. Once the desired performance is obtained the DCDT will automatically calculate the compensator coefficients and scaling parameters and generate software files to be used with the free SMPS Control Software Libraries.

The DCDT is topology independent which allows the most sophisticated converters to be analyzed. With a topology independent architecture, the tool requires a mathematical expression of the plant transfer function. This can be entered as a polynomial equation or in pole/zero form (up to 5th order systems). The tool also supports a data import option where the plant transfer function is a table of phase/gain vs. frequency data points that can be generated from a simulation environment or even from a network analyzer.
 
The DCDT currently allows users to develop voltage mode control and peak current mode control applications with support for average current mode control to be available shortly. Depending on the control scheme, different compensators may be required. The DCDT supports many different compensator types such as the digital 3-pole/ 3-zero (3P3Z), digital 2P2Z, digital PID, and analog type II/III. The analog type II/III compensators allow analog designers to input their existing analog compensator designs into the tool either by passive R/C components or by entering pole/zero frequency points. The tool will then generate the equivalent digital compensator streamlining the transition from analog to digital compensator design.

All MPLAB® X IDE. plug-ins, including this Digital Compensator Design Tool, are free, available and ready to install once the MPLAB® X IDE has been installed. Just follow the simple steps in the getting started tab to see all the available plug-ins and to install the DCDT.

The Digital Power Development Board is a demonstration board that provides the user a flexible measurement platform for all compatible Microchip dsPIC33’s Digital Power Plug-In Modules (DP PIMs).

DP PIM modules can be inserted into the mating socket in the middle of the Digital Power Development Board. All pins of the DP PIM are accessible via test loops or pin headers. The on-board Micro USB connector provides a DC power input to all circuitry. In addition, a mikroBUS™ socket is provided to extend functionality.
