This paper presents the use of a single-phase voltage-doubler Boost rectifier, to generate a controlled DC voltage, which is applied to a four-quadrant chopper. The transistor chopper controls the speed of a separately excited DC machine. The Boost rectifier permits the regeneration of energy from the motor to the single-phase mains, maintaining in all operating points a practically sinusoidal input current, with a THD of 2.5%. The balancing of the two filter capacitors is achieved by using and additional control loop. A low cost microcontroller is used to control the DC voltage and the motor speed.

An active voltage doubler utilizing a single supply op-amp for energy harvesting system is presented. The proposed doubler is used for rectification process to achieve both acceptably high power conversion efficiency (PCE) and large rectified DC voltage. The incorporated op-amp is self-biased, meaning no external supply is needed but rather it uses part of the harvested energy for its biasing. The proposed active doubler achieves maximum power conversion efficiency (PCE) of 61.7% for a 200 Hz sinusoidal input of 0.8 V for a 20 KΩ load resistor. This efficiency is 2 times more when compared with the passive voltage doubler. The rectified DC voltage is almost 2 times more than conventional passive doubler. The relation between PCE and the load resistor is also presented. The proposed active voltage doubler is designed and simulated in LF 0.15 μm CMOS process technology using Cadence virtuoso tool.

Rapid increases in the power ratings and continued miniaturization of semiconductor devices have pushed the heat flux of power electronics well beyond the range of conventional thermal management techniques, and thus maintaining the IGBT temperature below a specified limit has become a critical issue for thermal management of electric vehicle power electronics. Although two-phase cold plates have been identified as a very promising high flux cooling solution, they have received little attention for cooling of power electronics. In this work, a first-order analytical model and a system-level thermal simulation are used to compare single-phase and two-phase cold plate cooling for Toyota Prius motor inverter, consisting of 12 pairs of IGBT’s and diodes. Our results demonstrate that with the same cold plate geometry, R134a two-phase cooling can substantially reduce the maximum IGBT temperature, operate all the IGBT’s at very uniform temperatures, and lower the pumping power and flow rate in comparison to single-phase cold plate cooling. These results suggest that two-phase cold plate can be developed as a low-cost, small-volume, and high-performance cooling solution to improve system reliability and conversion efficiency for electric vehicle power electronics.

In this paper, a single phase dc to ac inverter with a low cost driver circuit was developed. The input source is a battery tank of four series-connected LiFePO4 batteries. The input DC power is then converted into the output AC power with 110Vrms and 60Hz. The proposed inverter is composed of a boost DC converter and a full bridge inverter. As for the circuit architecture, the boost converter is used to boost the battery tank voltage to 190V DC voltage bus. The DC voltage bus is then used to generate the output AC voltage by the full bridge inverter. A low price micro-controller unit HT66F50 was adopted for the controller of the proposed inverter. Moreover, instead of a common switch driver IC, a driver circuit with about 50% cost reduced was constructed for the full bridge inverter. A prototype with 300W rated output power was practically constructed and it can be seen that the total harmonic distortion is lower than 5%.

Abstract In this paper, a single-phase to three-phase converter is proposed to provide variable output voltage and frequency. The proposed topology employs only six IGBT switches, which form the front-end rectifier and the output inverter for the one step conversion from single-phase supply to output three-phase supply. The front-end rectifier permits bidirectional power flow and provides excellent regulation against fluctuations in source voltage. Moreover, it incorporates active input current shaping feature. An easy method to implement control strategy is proposed. This control strategy ensures nearly unity input power factor with sinusoidal input current over the operating range. Based on sensorless vector control technique, the proposed converter is used for the speed control of the three-phase induction motor. A low cost motor drive can be achieved using the proposed converter and control technique. Simulation and experimental results are carried out to analyse and explore the characteristics of the low cost drive system.

<span>Single-Phase Matrix Converter (SPMC) is an advanced circuit topology that offer advantages such as the capability to regenerate energy back to the input, sinusoidal input and output current and a manageable input current displacement factor. By considering the opportunity of an advanced SPMC topology, further exploration on DC to DC operation is proposed. The four-quadrant operation of switching algorithm was developed to control the SPMC circuit. The voltage and current profile of each quadrant was investigated to validate the proposed switching control algorithm. As part of four quadrants DC to DC operation, the safe commutation switching algorithm was also developed in order to solve the commutation problem due to the used of an inductive load. The pulse width modulation (PWM) techniques was utilized to synthesize the output of the proposed converter. Results from MATLAB/Simulink are presented to validate the proposed circuit operation.</span>
