  • Abstract
    This paper presents an improved topology of BLDC motor drive with a DC-DC Converter in the DC link and a combined Pulse Amplitude Modulation (PAM) and Pulse Width Modulation (PWM) technique. The goal is to separate the speed control and inverter commutation, in order to reduce switching losses and the inverter size and cost. Digital simulations of the proposed drive are performed with position sensors and with sensorless strategy and a comparison with the typical 3-phase inverter is realized.
