Abstract Industrial applications tend to involve a substantial assemblage of electronic devices, and it is imperative consider diverse charging requirements while these devices. This paper proposes three‐coil single‐input‐and‐dual‐output (SIDO) inductive power transfer (IPT) system meet the different The includes two independent output ports, providing constant voltage (CV) current (CC) for loads, respectively. In addition, zero‐phase angle (ZPA) operation can be achieved, thus avoiding injection reactive improving energy efficiency. Unlike previous related studies, receiver proposed SIDO IPT only one receiving coil pick up energy, eliminating unnecessary cross‐coupling complex decoupling circuits in traditional systems with multiple outputs. study first analyzes CC/CV theory detail, designs optimizes parameters by establishing an equivalent model. Then, conditions achieving zero‐voltage switching (ZVS) inverter are obtained analyzing sensitivity performance variation compensation capacitors. Finally, verification experimental prototype 2.5A CC 72 V CV established verify effectiveness system.
