DSP Based Battery Charger Control System Using Embedded Code Generation for Thyristor Rectifier

摘要

A battery is a device usually used to store power and deliver it to the energy system when thepower is not enough for the system. A battery charger consists of a three-phase thyristor, also known as siliconcontrolled rectifier (SCR), which is suitable for high power outputs such as induction heating and DC arcfurnaces. In this paper, a new DSP based controller using Embedded Code Generation (ECG) for the batterycharger is presented. This controller provides constant battery current and voltage control. The simulation of theproposed controller is created by using of computational PLL and C blocks in PSIM. The proposed controller istransmitted to SimCoder to obtain C-code. SimCoder generates the project outputs to the Code Composer Studio(CCS). In a battery charge controller design, when the users request to modify the codes for DSP and create aprototype, as well as creating C codes for CCS; the embedded code generation ECG provides a very fastsolution. As a simulation circuit, different output powers are simulated following the proposed controller. Theproposed controller is experimentally tested using a prototype. The experimental prototype includes voltagesensors, current sensors, the driver and chargers power module, DSP board. The proposed DSP based controlleris quite simple, understandable and easy to implement.
