In the following description, suffixes such as "module", "part", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no specific meaning by themselves. Thus, "module" and "component" may be used in a mixture.
To address the problems noted in the background, according to an aspect of an embodiment of the present application, an embodiment of a VR controller power processing apparatus is provided.
Example one
Referring to fig. 1, an embodiment of the present invention provides a VR controller power processing apparatus, which includes an MCU module 10, a power management module 20, a function module 30 with multiple voltage requirements, and a bluetooth module 40; the functional modules comprise a basic voltage functional module, a medium voltage functional module and a high voltage functional module; the MCU module is respectively and electrically connected with the basic voltage function module and the Bluetooth module;
the power management module 20 includes an input voltage terminal module (a single 1.5V dry battery), a first DC/DC converter 21, a second DC/DC converter 22, and a multiplier circuit module 23;
the input voltage end module is electrically connected with the first DC/DC converter and the second DC/DC converter respectively, and the output end of the first DC/DC converter is electrically connected with a VOD end in the MCU module; the first DC/DC converter is used for directly outputting voltage to a VOD end in the MCU module and outputting voltage to a basic voltage functional module electrically connected with the MCU module;
one output end of the second DC/DC converter is electrically connected with the multiplying circuit module, and the output end of the multiplying circuit module is electrically connected with the high-voltage functional module; the multiplying circuit module is used for outputting voltage to the high-voltage functional module in signal connection with the MCU module; the other output end of the second DC/DC converter is directly electrically connected with the medium voltage functional module, and the second DC/DC converter is used for directly outputting voltage to the medium voltage functional module in signal connection with the MCU module.
Referring to fig. 2, the VR controller power processing apparatus includes a power management module 20 (pink portion), an RF module (i.e., a bluetooth module 40), an MCU module 10 (light green), and a function module 30 (dark green + yellow). Wherein, the single section of 1.5V dry battery is used as the input end voltage of the power management module, namely the output voltage is 1.5V. Through the cooperation multiplier circuit module, above-mentioned VR controller power processing apparatus can export 3.3V, 5V and 12V voltage to satisfy the normal work of different functional modules. Regarding the different functional modules, only the IR LED Driver module needs 5V and the IR LED Connector module needs 12V voltage supply, and the rest of the functional modules (as the basic voltage functional module) need only 3.3V supply. The schematic diagram of the hardware design is shown in fig. 2.
The VR controller power supply processing device provided by the embodiment of the invention only adopts the structure that the VR controller power supply processing device comprises a first DC/DC converter, a second DC/DC converter and a multiplying circuit module, and then the second DC/DC converter is connected with a multiplying circuit to realize the output of voltage;
the first DC/DC converter is used for directly outputting voltage to a VOD end in the MCU module and outputting voltage (3.3V) to a basic voltage functional module electrically connected with the MCU module;
the second DC/DC converter is used for directly outputting voltage, namely 5V voltage, to the medium voltage functional module in signal connection with the MCU module; meanwhile, a second DC/DC converter is matched with the multiplying circuit module, and high-voltage output (12V) is realized through the multiplying circuit module, so that various different output voltages can be generated.
For example, in one embodiment, an input voltage a volts (e.g., an input voltage terminal module) is converted to an output voltage b volts by a second DC/DC converter. The output voltage of b volts is converted by the multiplying circuit template to generate the output voltage of c volts. Wherein c is n b, see also fig. 3;
wherein n is the number of the multiplying circuits of the multiplying circuit module; b is the input voltage at the input of the multiplier circuit. High voltage can be output through the effect of multiplier circuit module like this, and then richened voltage output and finally ensured VR controller power processing apparatus and can export to satisfy all the other different functional modules and normally supply power. In the prior art, different output voltages are generally required to be generated by modulation of a plurality of different DCDC power supply chips. However, the present embodiment can generate a plurality of different output voltages
Research shows that the VR controller generates energy consumption in the using process, so that the input voltage a is reduced. In general, the lower the input voltage a, the lower the power conversion efficiency of the DC/DC converter. Therefore, in the prior art, when the input voltage a is smaller than a certain threshold, the VR controller cannot be operated normally. However, even if the input voltage a is reduced by applying the VR controller power supply processing apparatus of the present embodiment, the reduction of the power supply conversion efficiency of the DC/DC converter is accompanied, but the multiplication circuit outputs a high output voltage c due to the action of the multiplication circuit module, and then the VR controller is supplied with the output voltage c at this time, so that the cruising ability is satisfied.
In summary, the VR controller power processing apparatus provided in the embodiment of the invention keeps the output voltage b unchanged as the input voltage a decreases. However, as the power conversion efficiency of the DC/DC converter is reduced, the switching frequency of the DC/DC converter is higher and higher, and the duty ratio of each switching cycle is larger and larger. Therefore, more and more capacitance functions are used for the multiplying circuit module in unit time. More and more capacitors are used for the multiplying circuit module to store energy. The capacitance value of the capacitor is not changed, and the voltage at two ends of the capacitor is higher and higher when the stored energy is more and more. Therefore, higher output voltage c can be output to meet the use requirement of the VR controller, and the cruising ability of the VR controller is improved.

As shown in fig. 4, the VR controller power supply processing apparatus reduces the complexity of the circuit design.

In the above circuit structure, as the output voltage of the single 1.5V dry battery decreases, the output voltage 5V of the second DCDC converter remains unchanged.
