This paper introduces a designer-side switching loss analysis characterized by evaluating parasitic capacitor's energy variation and related losses for integrated synchronous Buck converters in CMOS technology (ISBC). After categorizing losses related to power FET parasitic capacitors' charging/discharging currents as charging/discharging losses (C_loss), it is noticed that the ratio of charging/discharging...
In this paper, a review of switching loss mechanisms for synchronous buck voltage regulators (VRs) is presented. Following the review, a new simple and accurate analytical switching loss model is proposed for synchronous buck VRs. The model includes the impact of common source inductance and switch parasitic inductances on switching loss. The proposed model uses simple equations to calculate the rise...
This work discusses an exact mathematical approach of calculating the IGBT turn-on, turn-off and on-state energy losses. Instantaneous voltage and current values are studied, linearized and employed to formulate the equations needed to calculate the IGBT switching loss. The inverter employs a switching pattern commonly known as sinusoidal PWM (SPWM). With this popular switching pattern, switching...
