PWM控制的单相逆变电源系统设计 摘 要 随着国民经济的高速发展和国内外能源供应的紧张，电能的开发和利用显得更为重要。尤其是面对经济和科学技术发展的今天，一款稳定，易携带的交流电源正是我们现在方便生活重要的一种途径。目前，国内外都在致力于发展新能源，太阳能发电，风力发电，潮汐发电等。但是这些电能最终输出的都是不稳定的交流电，要想得到一款稳定的交流电源，逆变技术就要发挥极大的用处了。 本文设计的单相PWMBoost电路和全桥电路的组合。控制电路采用的是IR2110控制，产生PWM波脉冲宽度调制Design of Single Phase Inventer Power System Controlled of Pwm Abstract With the high-speed developing of national economy and the shortage supply of world electrical energy supplies, the development and utilization of electric power is more important. Especially in the face of economic and scientific and technological development today, a stable, easy to carry AC power is important that we are now a way of life convenient. At present, domestic and foreign are committed to the development of new energy sources, solar power, wind power, tidal power generation. But these are unstable final output power AC, in order to get a stable AC power inverter technology will play a significant useful. This design of single-phase PWM inverter power belongs to AC power, voltage-feedback control method by adjusting the duty cycle of the pulse width of the drive voltage is changed to adjust and stabilize the output voltage. The main circuit Boost circuit is used in combination and a full-bridge circuit. Control circuit uses a IR2110 control, PWM wave trigger bridge circuit, the boost circuit, stable output voltage, the paper also designed the overcurrent protection circuit to improve system stability. This detailed analysis of the inverters work process, and pushed to the important formula, the final design of the design of the simulation to verify the feasibility of the system.
