Small-signal analysis of boost converter fed permanent magnet DC (PMDC) motor for electric vehicle applications is performed, and hardware implementation is realized in this paper. Extensive analysis is performed to identify the relevant steady-state and dynamic features of the proposed system with small-signal linearization, and relevant transfer functions are formulated. The nonlinear equations of the system are derived and then linearized around a stable operating point to construct a small-signal model. Transfer functions relating the control of the converter to the motor speed and control to input current are derived symbolically using computerized symbolic algebra in MathCAD. The control-to-output transfer functions are obtained by introducing perturbation in state variables, equating AC and DC quantities and proceeding with AC quantities. The principle of operation, operation modes, small-signal analysis, experimental verification, and the effectiveness of the speed control are discussed and presented. An experimental prototype is implemented using dSPACE DS1103-based digital signal processor, and the proposed model is used for online parameter tuning of the speed controller. The speed control dynamics and transient response are investigated under sudden load changes. The overall system performance is evaluated and verified experimentally based on a speed feedback control scheme for validation purposes.

This paper introduces a novel topology of the proposed converter that has these merits: (i) the topology of the converter is based on conventional boost and buck-boost converters, which has caused its simplicity; (ii) the voltage gain of the converter has provided higher values by the lower value of the duty cycle; (iii) due to the use of high-efficiency conventional topologies in its structure, the efficiency of the converter keeps its high value for a great interval of duty cycle; (iv) besides the increase of the voltage gain, the current/voltage stresses of the semiconductors have been kept low; (v) the continuous input current of this converter reduces the current stress of the capacitor in the input filter. It is worth noting that the proposed converter has been discussed in both ideal and non-ideal modes. Moreover, the operation of the converter has been discussed in both continuous/discontinuous current modes. The advantages of the converter have been compared with recently suggested converters. In addition, the different features of the converter have been discussed for different conditions. In the small-signal analysis, the appropriate compensator has been designed. Finally, the simulation and experimental results have been reported for 90 W output power, 90 V output voltage, 3-times voltage gain, and 100 kHz switching frequency.
