摘要：This paper describes the design and implementation of high power DC-DC step- up converter using analog control circuits and speed control of DC motor using TMS320F240 DSP. In this technique a 24V DC input supply is converted into 135V DC by two-stage conversion. The full bridge topology is proposed for step up the DC voltage. The output of step-up converter is provided to the capacitive accumulator circuit which consists of 1.2F capacitor bank in it. The capacitive accumulator is mainly used to compensate peak power demand of the load for a transient period when sudden changes occur at load side and to store the energy under regenerative braking condition of DC motor. The capacitive accumulator circuit provides a constant voltage to the DC chopper under normal working condition. The closed loop speed control of DC motor is achieved using TMS320F240. The current and speed feedback are compared with their references respectively to achieve the speed control of DC motor which is used in military application.
