Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as practical to this
Novel restriction.
Fig. 1 is a kind of standby driving plate according to the utility model embodiment, as shown in Figure 1, the driving plate includes:
Charge relay is arranged on the charging circuit of driving plate bus, for the control signal according to master board,
When the driving plate enters standby mode, the current supply circuit of the driving plate charging circuit is disconnected；
The main relay is arranged on driving plate bus, in parallel with the charge relay, in the driving plate

That is, the utility model embodiment is on the charging circuit of driving plate by being arranged charge relay, and
It on driving plate bus, is arranged in parallel with the charge relay by main relay, and passes through charge relay and main relay
Switching, realizes the Zero-power-consumption standby of driving plate.
Moreover, the utility model embodiment only needs to be arranged on the charging circuit of driving plate charge relay, that is,
It says, the utility model embodiment can be achieved with the standby zero-power of driving plate only with the movement of relatively simple component, so
The cost that the scheme of the utility model embodiment is realized is relatively low, can be applied in plurality of devices, for example, various convertible frequency air-conditioners
In.
It should be noted that in order to realize that charge relay and main relay can once switch all electricity of driving plate
Source, so the driving plate of the utility model embodiment uses full DC drive circuit, also, the charging of the utility model embodiment
Before the current supply circuit of the driving plate and the node of loop of power circuit is arranged in relay, to realize that driving plate enters standby mode
When standby zero-power-consumption.
When it is implemented, it is the control signal according to master board that the utility model, which implements the charge relay, in institute
When stating driving plate and entering standby mode, the current supply circuit of the driving plate charging circuit is disconnected, the main relay is according to institute
The control for stating driving plate disconnects the main current supply circuit of the driving plate when the driving plate enters standby mode.
In view of driving plate there is a situation where it is fully powered-off, so the charge relay of the utility model embodiment is by leading
Control is opened and disconnected to control panel, and when pretrigger driving plate, master board needs first to control charge relay closure, thus
The current supply circuit conducting for realizing driving plate charging circuit, to charge to bus capacitor, and after being spaced the predetermined time, by driving
The control process control main relay of movable plate is closed, to realize the starting of driving plate.
