DC Inverter Driver Board for scroll/rotary compressors HMD4W-3A

The inverter driver is specially designed for air conditioning DC/AC inverter compressors, which is integrated with Rectifier Bridge, Power on/off, Charging Circuit, DSP chip control circuit, IPM module, communication circuit, capacitor board & EMC filtering board. Users only need to connect power source & send control signal to change compressor's frequency.

u00bbu00bb Combined with years of experience in project commissioning, independent research anddevelopment. The hardware of inverter drivers are designed to fit compressors from 0.5HP to 15HP.Developing inverter driver for new compressors will only need 7 working days.u00bbu00bb SVPWM no position sensor sine wave control can effectively reduce the higher harmoniccomponents, motor vibration, torque ripple and noise.u00bbu00bb Closed-loop control can ensure compressor to start smoothly, reduce compressor's startup current,and reduce the impact on the electric grid.u00bbu00bb Weakening & MTPA control can improve the operating frequency range of compressor.u00bbu00bb Double-loop feedback control strategy: the outer ring (speed loop) to ensure the unit operated understable frequency, the inner ring (current loop) to ensure the unit accurate real-time output torque.u00bb Wide operating voltage range: it can be operated stably under 1Ph 175V-265V of power sourcevoltage.u00bbu00bb The driver can achieve high efficiency, small size, high integration, and it is convenient to produce,test and maintain.u00bbu00bb With a variety of protective function (under-voltage, over-voltage, over-current, high temperature,etc.), and use fast DSP chip to make all the protection function get rapid response to ensure reliablesystem operation.

This inverter driver can drive many popular compressors such as Hitachi E405DHD38D2YG, Sanyo C-SDP205H02B, SIAM ANB/ANE series compressors, etc.

Typically the inverter driver has three components, All of the parts ensure the function of changing compressor frequency. Components are as follows:Inverter driver board, Capacitor & Filtering board and Reactor.The debugger is used to control the inverter board to change compressor speed when there is not a main controller board ready, it gets feedback data from the inverter such as setting frequency, compressor current, input current & voltage. The inverter board can be controlled by PLC, main controller board or debugger. Debugger is very convenient during testing.The following is a Youtube video link to show the connection & testing of the debugger with inverter drivers:http://youtu.be/gow2sGOhj80
