Embodiment Construction
[0014] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0015] In one example, see figure 1 As shown, a voltage converter includes a rectification device 100, a front-stage energy storage device 200, a DC-DC conversion device 300, a rear-stage energy storage device 400, a control conversion device 500 and a switch control device 600,
[0016] The rectification device 100, the front-stage energy storage device 200, the DC-DC conversion device 300, and the rear-stage energy storage device 400 are connected in sequence. The rectification device 100 is connected to the control lines A-, B-, and C-, and the receiving control system passes the control line A- , B-, C- input switch control signals and convert the received switch control signals into smooth DC output to the front-stage energy storage device 200, the front-stage energy storage device 200 is also connected to the...

The invention relates to a voltage converter, which specifically includes a rectification device, a front-stage energy storage device, a DC-DC conversion device, a rear-stage energy storage device, a control conversion device, and a switch control device. The rectification device, the front-stage energy storage device The energy device, the DC-DC conversion device, and the rear-stage energy storage device are connected in sequence, the front-stage energy storage device is connected to the positive pole of the power supply or the ground electrode, and the rear-stage energy storage device is connected to the drive device and provides the power for the drive. The device provides electric energy, the drive device is connected to the load to be driven, the control conversion device is respectively connected to the control line and the switch control device, and the switch control device is connected to the subsequent energy storage device and the load. By implementing the above-mentioned voltage converter, the high-voltage control signal can be carried by a low-voltage load, and the low-voltage control signal can be carried by a high-voltage load, or the voltage converter can be added to a load that is inconvenient to make a high voltage to make it a High voltage load, so as to realize the matching of switch control signal and load.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a voltage converter. Background technique [0002] At present, voltage converters are widely used in the power supply system of electronic equipment. Take the voltage converter used in the four-wire RGB lighting control system with driving capability as an example. Compared with the traditional lighting control system, the voltage converter with driving capability The four-wire RGB lighting control system saves a V+ line or GND line, which leads to no stable power output. Not only can it not achieve the same effect as the traditional lighting control system in terms of voltage conversion, but also requires the control signal output by the system It needs to match the load. For example, the 12V control signal must match the 12V load, and cannot be used to control the 5V or 24V load. Similarly, the 5V control signal must match the 5V load, and the 24V control signal must ...
