Believe that equipment can include the control circuit of the power module stand-by power consumption shown in Fig. 2, wherein, the control of power module stand-by power consumption
The energization input for needing power supply module in busbar and communication equipment that circuit includes is connected.Wherein, power supply module is needed to wrap
Include radio-frequency module.
Referring to Fig. 7, Fig. 7 is the structure chart of another communication equipment disclosed in the embodiment of the present invention.As shown in fig. 7, should
Communication equipment can include the control circuit of the power module stand-by power consumption shown in Fig. 3, wherein, the control of power module stand-by power consumption
The energization input for needing power supply module in busbar and communication equipment that circuit processed includes is connected, wherein, need power supply module can be with
Including radio-frequency module.
Wherein, a voltage isolated variable can be increased in the communication equipment described by Fig. 6, Fig. 7, inside power module
Circuit, after power module receives the standby command that monitoring module is issued, former and deputy side dsp chip first respectively by pfc circuit and
DC/DC converters are closed, and then output enable signal to voltage isolated variable circuit, trigger voltage isolation by secondary dsp chip
Translation circuit is worked so that voltage isolated variable circuit can be closed with output control signal control primary side auxiliary source, so as to
It is effectively reduced the stand-by power consumption of power module.
A kind of also disclosed control method of power module stand-by power consumption of the embodiment of the present invention.This method can include following
Step:
A, the pfc circuit of power module receive the alternating voltage of input, and export DC voltage to the DC/DC of power module
Converter;The DC voltage conversion into stably and controllable DC voltage, and is exported busbar by DC/DC converters;
B, the primary side auxiliary source of power module receive the alternating voltage of input, and alternating voltage is converted into suitable power supply mould
The supply voltage of the primary side dsp chip of block, and input primary side dsp chip and be powered;And, alternating voltage is converted into be adapted to
The supply voltage of the secondary dsp chip of power module, and an input of the dual input OR gate of input power module;Power supply mould
The secondary auxiliary source of block is received after the DC voltage on the DC voltage or reception busbar of DC/DC converters output, by direct current
Pressure is converted into being adapted to another input of the dual input OR gate of the supply voltage input power module of secondary dsp chip;Power supply
The supply voltage input secondary dsp chip of primary side auxiliary source or secondary auxiliary source is powered by the dual input OR gate of module;
C, the secondary dsp chip of power module receive the standby command that monitoring module is issued, and standby command is notified into former
Side dsp chip;Primary side dsp chip, secondary dsp chip respond standby command and send a control signal to pfc circuit and DC/DC respectively
Converter, to close pfc circuit and DC/DC converters;
D, the voltage isolated variable circuit of power module receive the DC voltage of DC/DC converters output or received on busbar
DC voltage be powered, and response secondary dsp chip input the work of enable signal enabling, and output control signal control
Primary side auxiliary source processed is closed.
In one embodiment, the voltage isolated variable circuit output control signal control primary side auxiliary source of power module is closed
Closure is included:
The voltage isolated variable circuit output control signal of power module is to primary side auxiliary source and the alternating current of power module
The switching device connected between pressure input port, the alternating voltage of primary side auxiliary source and power module is disconnected with controlling switch device
Connection between input port, so as to control primary side auxiliary source to close.
In another embodiment, the voltage isolated variable circuit output control signal control primary side auxiliary source of power module
Closing includes:
The voltage isolated variable circuit output control signal of power module is to primary side auxiliary source, to control primary side auxiliary source
Signal level reduction is enabled, so as to control primary side auxiliary source to close.
In a kind of control method of power module stand-by power consumption disclosed in the embodiment of the present invention, it can increase inside power module
Plus a voltage isolated variable circuit, after power module receives the standby command that monitoring module is issued, former and deputy side DSP cores
Piece first respectively closes pfc circuit and DC/DC converters, then outputs enable signal to voltage isolation change by secondary dsp chip
Change circuit, the work of trigger voltage isolated variable circuit so that voltage isolated variable circuit can control primary side with output control signal
Auxiliary source is closed, so as to be effectively reduced the stand-by power consumption of power module.
