Circuit for detecting failure of zero voltage switching
Provided is a resonant power conversion apparatus including a gate control circuit that controls a first switch to enter an On state and a second switch to enter an Off state at a first stage and controls the first switch to enter the Off state and the second switch to enter the On state at a second...

| description | Provided is a resonant power conversion apparatus including a gate control circuit that controls a first switch to enter an On state and a second switch to enter an Off state at a first stage and controls the first switch to enter the Off state and the second switch to enter the On state at a second stage, a first current transformer that applies current to the first switch at the first stage and applies current to the second switch at the second stage, a load connected to the first current transformer in series, a second current transformer connected to the second switch, and a microcontroller unit (MCU) that determines whether to be zero voltage switching or non-zero voltage switching based on a current flowing in the first current transformer and the second current transformer in a process of transitioning from the first stage to the second stage. |
