Transformer parasitics such as leakage inductance and self-capacitance are rarely calculated in advance during the design phase, because of the complexity and huge analytical error margins caused by practical winding implementation issues. Thus, choosing one transformer architecture over another for a given design is usually based on experience or a trial and error approach. This paper presents analytical...

Flyback converters are widely used in several applications, however, with this topology it is very challenging to achieve high voltage operation especially with very high step-up ratio (>500) within limited space. This paper presents a new flyback-based topology which utilizes primary parallel and secondary series transformer connection in order to achieve very high step-up ratio (up to 650) as...
Micro-inverters convert direct current (DC) from a single solar panel to alternating current (AC). Peak current control is a simple way to regulate the output current of the micro-inverter. In this way, the shape of the current reference will determine the total harmonics distortion (THD) of the output line current. However, several factors like valley switching turn-on delay and equivalent capacitor...
