“…To provide a level of abstraction, a switching duty cycle is defined to be the amount of time turning the SRs on or off as a ratio of the switching period: D sw = 4t sw /T s . The peak gate current can then be found with (6). Through simple manipulation, the RMS gate current can be found with (7) as a function of the switching duty cycle and gate charge of the SRs…”

“…Resonant gate drivers (RGDs) with continuous inductor current are able to transition the power MOSFETs quickly, but experience excessive conduction loss [1]- [5]. Discontinuous current drivers are subject to slow transitions and higher peak currents [6]- [8], but have the benefit of lower conduction loss. Current source drivers (CSDs) are a subclass of discontinuous current RGD where the inductor current is charged to a nonzero value to transition the power devices.…”

In this paper, a dual-channel current source driver is presented as an efficient means of driving complementary switches. The driver transfers charge between the gates of the power devices through a single magnetic core with a discontinuous current. This promotes lower conduction loss than continuous current resonant gate drivers (RGDs), and lower component count or conduction loss than existing discontinuous current RGD applied to complementary switches. In addition, controlled switching speed is achieved through nonzero inductor current resulting in lower current stress, and faster switching compared to some pulse RGD circuits. There is good correlation between the analysis and experimental results of a 1.8-MHz prototype.

This paper proposes a power supply circuit for gate drive units (GDUs) that uses a one-turn transformer, which gives advantages in terms of cost and loss reduction. The structure of the proposed one-turn transformer consists of a primary winding in which the number of turns is one and a secondary winding in which there are multiple number of turns. The proposed one-turn transformer is connected in series with a switching device of the main circuit in order to obtain power for the GDUs. The proposed power supply circuit can be applied to all types of main circuit topologies such as a multilevel converter topology or matrix converters, in addition to a conventional six-arm inverter. In this paper, the design method of the one-turn transformer and its characteristics are described based on an equivalent circuit and fundamental experimental results with a step-down chopper. Besides, the proposed power supply circuit for GDUs is tested in a two-level three-phase inverter. Secondly, the obtained power for GDUs from the proposed one-turn transformer with three connection points is investigated by harmonics analysis from the viewpoint of core size and other parameters. Finally, experimental results confirm that the GDU in the two-level three-phase inverter with switching frequencies of 12.5 kHz and 16 kHz is operated by the proposed self-supplying gate power supply circuit without an external power source.

* This paper introduces a new resonant gate driver for high-frequency synchronous buck converters. With a coupled inductor, this circuit can drive both the top and bottom switches in resonance. Furthermore, some of a switch's turn-off energy can be transferred and utilized in the turn-on of another switch. The operation principle is discussed and the driving loss is analyzed. Simulation and experimental results prove that this new gate driver can greatly reduce driving loss compared with conventional gate drivers. The proposed driver is well suited to high-frequency applications.
