The control algorithms have been implemented on the AT90PWM3, a low-cost lowpower single-chip microcontroller, achieving up to 16 MIPS and suitable for the control of DC-DC buck-boost converters, permanent magnet synchronous machines, threephase induction motors and brushless DC motors. This device integrates:
• 8-bit AVR advanced RISC architecture microcontroller (core similar to the ATmega 88)
• 8K Bytes of In-System-Programmable Flash memory
• 512 Bytes of static RAM to store variables and lookup tables dedicated to the application program
• 512 bytes of EEPROM to store configuration data and look-up tables
• one 8-bit timer and one 16-bit timer
• 6 PWM channels optimized for Half-Bridge Power Control
• an 11-channel 10-bit ADC and a 10-bit DAC
• 3 on-chip comparators
• a programmable watchdog timer with an internal oscillator
