Special Issue Information

Dear Colleagues,

With the increase of autonomous and electric vehicles such as drone, electric scooters and bikes, the miniaturization of power electronics becomes of critical importance. The development of small and efficient converters for driving these vehicles with the minimal weight and size is creating new ways of displacement. In this sphere, power integrated circuits are a key part for driving electric machines. In general, a power integrated circuit includes a power stage and the intelligence which allows controlling such machines, however there are other many types of integrated circuits for power electronics which also play important roles in the power conversion such as monitoring integrated circuits.

This special issue aims to gather articles which will cover a vast range of integrated circuits for power electronics including battery monitoring and protection, low power regulators, switching regulators, drivers for wide band semiconductors such as Gallium Nitride and Silicon Carbide, high-voltage and current meters. Particularly the special issue is focused on modeling, design methodology, optimization techniques and applications. Experimental validations at different power levels will be appreciated. In addition, comprehensive methodologies for design procedures are also valuable.

We present a high-stability regulation circuit to ensure the safety of a device within a wide range of the back-sink current for a USB Type-C interface application. The proposed adaptive linear pole–zero tracking compensation can linearly compensate for the changes in the back-sink current, thereby adaptively canceling the pole–zero changes caused by the current changes. The simulation results show that the phase margin remains greater than 60°. Meanwhile, the loop bandwidth changes between 45 kHz and 135 kHz, when the current increases from 0 A to 1 A, ensuring excellent loop stability. The high-stability regulation circuit is realized in a standard 180 nm CMOS process with an area of 0.4 mm × 0.6 mm. The chip regulates an output voltage from 4.5 V to 5.5 V with 1 A current capacity and 100 mV maximum dropout voltage with the help of the adaptive linear pole–zero tracking compensation.

This paper presents a maximum power point tracking (MPPT) algorithm in a solar photovoltaic (SPV) system that requires fewer sensors, is easy to implement, and offers a good tracking efficiency and speed. Among various MPPT algorithms found in literature, the perturb and observe (P&O) algorithm is most popular as it required less complex circuitry and is easy to implement, but it suffers against fast-changing environmental conditions mostly in the case of partial shading conditions and requires two sensors, i.e., voltage and current. This paper presents the one sensor-based method based on the modified converter design which eliminates the effect of partial shading conditions as well as the fast-changing environmental condition. The presented MPPT algorithm was implemented and tested using an FPGA-based NI-sbRIO card interfaced with Labview software. Full article
