Part Number: UCD3138HSFBEVM-029 Other Parts Discussed in Thread: UCD3138 , UCD3138FW-HSFB , Hello,
Recently, we received two UCD3138HSFBEVM-029 modules. We connected an input of 48Vdc but we didn’t obtain the 12Vdc at the output. It seemed that the firmware…
Part Number: UCD3138FW-HSFB Other Parts Discussed in Thread: UCD3138 Hello. I want to use UCD3138 to make a phase-shifted full-bridge circuit. I see that the development board uses voltage and current dual-loop control. Can UCD3138 achieve single-loop output…
Part Number: UCD3138FW-HSFB Other Parts Discussed in Thread: UCD3138 Based on UCD3138, a full-bridge hard-switching power supply was used to test the waveform of the primary winding of the transformer.
Some of them are normal, and some of them appear as…
Part Number: UCD3138FW-HSFB Other Parts Discussed in Thread: UCD3138 According to the UCD3138 full-bridge hard-switch development board, four full-bridge hard-switching power supply prototypes were made.
The input Vin: 20V~50V, no-load test.
When the input…
I first used my own code.It has the problem.then I tried TI EVM code, UCD3138FW-HSFB — UCD3138 Hard Switch Full Bridge.I downloaded form hear UCD3138FW-HSFB 固件 | TI.com.cn ( www.ti.com.cn/.../UCD3138FW-HSFB),The problem is the same.
I use CCS10.31 version, and the ARM compilier Tool version is 5.2.9
I downloaded the fixed SDK from TI webpage: UCD3138FW-HSFB — UCD3138 硬开关全桥, https://www.ti.com.cn/tool/cn/UCD3138_FW_SDK
and then I built workspace, and import this UCD3138FW…
Most of our reference designs have firmware code derived from the EVM we publish. You can use our Hard-switching Full bridge code and modify to use on this reference design.
Per Ti policy, a click wrapped firmware need be generated, it takes some time to get it ready. I can recommend that you can download TI EVM HSFB code ( https://www.ti.com/tool/UCD3138FW-HSFB ). It is voltage mode control. Then you can modify…
If by "reference" you mean the firmware that supports the CCCP feature, then you can download the hard switch full bridge EVM code that implements the CCCP feature at the following:
The UCD3138 can be used for a 3kW AC-DC design. Typically, this requires two UCD3138s: one UCD for the PFC stage, and another on the secondary side for the DC-DC.
You can obtain our reference firmware for PFC and DC-DC EVM designs at http://www…
