WIPO Patent Application WO/2020/042473
Kind Code:
A1
Abstract:
Disclosed in the present application are a driver circuit, a switch control circuit, and a cooking appliance. The driver circuit comprises a driving signal input end, a high voltage end, a low voltage end, and at least two switch branches. Each switch branch is connected to the driving signal input end. The at least two switch branches comprise a first switch branch and a second switch branch. The first switch branch is connected to the high voltage end by means of a first connection branch, and the second switch branch is connected to the low voltage end. The switch branches are connected by means of a second connection branch. Both the switch branches and the first connection branch are provided with components. The components can control the current of the branches on which said components are located. The driver circuit is configured such that when any one of the components fails, the electric parts do no operate under the condition of non-active driving, thereby ensuring the reliability of the circuit. Said circuit is particularly suitable for export products.
