【Electric Competition】Three-phase half-bridge module

Overview

Circuit analysis of
three-phase and single-phase uncontrolled rectification is shown in the figure below. If uncontrolled rectification is used, just solder the diode.

Three-phase and single-phase inverter circuits are shown in the figure below. If you use the module as an inverter, you only need to weld the MOS tube. After output, you need to add another level of filtering.

The schematic diagram shows that
when using uncontrolled rectification, only the diode can be welded, the input is the AC side UVW, and the output is the DC side. When used as an inverter, just weld the MOS tube, the input is the DC side, and the output is the AC side UVW.
Maximum Vdss of MOS tube: 100V, maximum overcurrent: 33A.
Maximum reverse voltage of diode: 100V, average rectified current: 5A.
Driver chip IR2103 power supply: 10-20V

RAM and ROM
I would like to ask the experts about the 51 memory problem. When writing a program, we will store the data table in 1000H, such as ORG 1000H DB 09H,90H... So, are these data in RAM or ROM? The on-chi

The problem of increasing resistance value
The resistance across the power supply of my circuit increases from 1.1M to 6.5M in a short period of time. I don't know why? Or is it because of the capacitive reactance of the capacitor that the tot
