An improved particle swarm optimization (IPSO) is used to solve economic dispatch problem (EDP). The IPSO has two position updating strategies. In the early stage of iteration, the individual in the population updates the position according to its own best experience with a large probability. In the later stage of iteration, the individual updates the position according to the best experience in the population with a large probability. In addition, the IPSO introduces a mutation operator after position updating, which can increase the diversity of population and prevent the premature convergence. IPSO has been used to solve EDP with valve point effect. The experimental results show that IPSO is an effective algorithm to solve EDP.

This paper presents an application of the well known SPWM technique on a voltage stabilizer, using a microcontroller. The stabilizer is AC/DC/AC type. So, the system rectifies the input AC voltage to a suitable DC level and the intelligent control of an embedded microcontroller regulates the pulse width of the output voltage in order to produce through a filter a perfect sinusoidal AC voltage. The control program on the microcontroller has the ability to change the FET transistor firing in order to compensate any input voltage variation. The applied software using the microcontroller's interrupts managed to achieve concurrency on the running program.

“…When pin P1D is modulated and P1B is placed in its inactive state, the negative half cycle of sinusoidal output can be achieved. Similarly, when pin P1B is modulated and P1D is placed in its inactive state, the positive half cycle of sinusoidal output can be obtained, as can be seen in Based on the optimal frequency ratio 84, the LC filter circuit is designed and placed at the output of the PWM inverter to filter out most harmonic contents other than those which are fundamental [36].…”

A novel short-circuit self-heating (SCSH) control system was developed in this thesis to achieve the preheating of lithium-ion (Li-ion) batteries operated in extremely cold weather (<-30°C). The proposed system relies on the internal resistance of batteries and the short circuit current to heat up batteries using Joule heating. Experiments show that the SCSH control system can heat up the commercial Panasonic 18650 Li-ion batteries from-30°C to 0°C in 43 seconds, with less than 5 percent of the battery capacity consumed. The proposed heating system outperformed both external convective air heating and alternating current (AC) heating, in terms of heating time and energy consumption. Furthermore, a DC to AC battery power inverter was developed to implement the AC heating and to make the battery pack available for household appliances. This inverter employs a microcontroller using the direct pulse width modulation (DPWM) technique. The inverter achieves power output at various frequencies through programming, without changing the design of the circuit board. The optimal frequency ratio can be obtained theoretically, validated through MATLAB simulation, and was further examined through experimentation. The selected frequency ratio enables the DPWM signals to stimulate the designed inverter to produce high quality sinusoidal voltage.
