“…3), there are no main-circuit-topology constraints and this can be widely used. The circuit configuration that uses capacitors in pairs is used mainly in the isolated power supply circuits at utility frequency (10) (11) and has a proven performance record. Unique rectifier circuit As shown in Fig.…”

Many techniques have been proposed as power supply methods for high-side gate drivers. However, most techniques that do not depend on the topology of the main circuit have drawbacks related to the size and cost. This paper proposes a novel floating power supply based on capacitive isolation. The proposed circuit is designed to operate independently of the main circuit, and it is cheaper and smaller than conventional circuits. The proposed method is applied to a diode-clamped multilevel topology and is validated by experiments.

“…As a second step, capacitive isolation 13 using a nesting capacitor structure was proposed, 14 and a similar circuit was incorporated into the conventional circuit to obtain a basic configuration for insolation between DC input and output 15 (below referred to as “isolation circuit”). In Reference [15], operation principle of the isolation circuit during powering and regeneration was demonstrated, and the feasibility of power transfer was confirmed via circuit response analysis in every mode.…”

This study aimed to develop a power supply system without a traction transformer for weight reduction and downsizing. Transformer‐less power supply is expected to realize step‐down, rectification, isolation, and motor drive using a high‐voltage silicon carbide power device. The primary challenge of this study was developing a novel circuit that isolates the motor drive circuit from the AC line without using the traction transformer. Accordingly, we devised a flying capacitor circuit to solve the existing problems and achieve capacitive isolation. Subsequently, we devised a nesting capacitor as a short‐circuit prevention measure. In this study, the operation of the isolated circuit was verified by numerical simulation, complemented by experimental verification of the proposed circuit.
