HT45F0074A Half-bridge Induction Cooker

Overview

My induction cooker at home frequently blows its tubes, burning out a bunch of components. So I thought I'd experiment with a half-bridge design. After researching, I found Holtek's solution to be simple, clear, and with complete documentation. Therefore, I'm going to replicate it according to the official documentation to see how it performs. This 3500W half-bridge induction cooker uses the HT45F0074A dedicated chip. The schematic and PCB layout are from Holtek Semiconductor (China) Co., Ltd.'s official demo materials. Those interested can download the relevant BOM, schematic, PCB layout, source code, and other files from their official website.

Every time I open a project, there is a prompt "the following access path *** cannot be found". How can I remove it?
The reason is: a certain file of the project was copied to the *** folder, and then it was deleted in the *** folder.
Tsinghua University-Oscilloscope Test Principles
High power driver amplifier 55453 replacement problem, please recommend
Our downhole instruments transmit downhole signals to the ground through several thousand meters of cables. Currently, we use sn55453 or sn75453 to drive Manchester code signals to the ground, but the
The pins of the 51 microcontroller must be processed when not in use.
For example, P0 should be pulled up. VPP should be connected to power, RESET should be connected to ground, and what else?
Resistor shunt counter
The resistor parallel counter can calculate the resistance value of up to five resistors in parallel.
What is my first wish/goal for 2013?
[color=blue][size=4][b]After tomorrow, we will say goodbye to 2012 and welcome the brand new 2013~~~ No matter how much reluctance or reluctance there is in the past year, let it pass away with time!
