Building-integrated photovoltaic (BIPV) arrays, which are installed on the roofs of buildings as part of urban solar power generation, have created a demand for high-power and high-density photovoltaic (PV) modules to produce high-output power in a limited area. In this paper, a high-power PV module using a shingles technology is designed. When the vertical and horizontal dimensions of the module were 201.78 cm × 96.75 cm in the same area as that of the conventional PV module, the number of cell strips reached 390. When six 65-interconnection shingled strings were connected in series, the output power of 367.8 W was achieved. Compared with a conventional PV module of the same area, the output power was 8% greater.

The linear power amplifier with high-output power in the broadband frequency is the critical component required by exciting the electromagnetic acoustic transducer (EMAT) to generate ultrasonic guided wave (UGW). The methods to realize the output of a high-power signal in the linear amplification mode and to expand the bandwidth at high-output power are seldom reported. To solve these problems, a power amplifier with differential structure is developed by using the parallel amplification architecture and the broadband feedback circuits. The proposed power amplifier uses a differential structure to suppress the even harmonic waves and remove the disruptions. Each branch of the differential structure consists of five linear power amplifier modules with output terminals connected in parallel to increase the output power. Also, the negative voltage feedback is used to extend the bandwidth of the power amplifier. The experimental results show that the −3 dB bandwidth of the amplifier is from 40 kHz to 2.5 MHz, and the transient output power is greater than 1 kW. The power amplifier can drive the EMATs to generate ultrasonic guided waves. Because of the high-output power and good linearity, the proposed power amplifier has excellent potential for EMAT UGW applications.
