Since the No. 4 blast furnace of Handan Iron and Steel was put into operation in 1993, its external equipment has been seriously aged, and the original PLC control system TDC3000 of the hot blast furn...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
System Overview
The system consists of a signal preprocessing circuit, a single-chip computer AT89C2051, a systematic LED display module, a serial port data storage circuit and system software...[Details]
One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
This paper describes the design method of electronic multifunctional watt-hour meter, the key technology of hardware design and the software design process. Taking NEC's μPD78F0338 microcontroller ...[Details]
When developing electronic products with processors, how to improve anti-interference ability and electromagnetic compatibility?

Preface
DS18B2 is generally used in conjunction with a single-chip microcomputer, and there are few reports on
the interface between
DSP
and DS18B20. Therefore, this article introdu...[Details]
introduction
Frequency characteristic tester
Also known as sweep frequency meter or frequency response analyzer, it uses a rectangular oscilloscope with internal scale as
a displ...[Details]
The embedded network module series products of Yingchuang Company all have a streamlined ISA expansion bus, which usually includes several address buses, 8-bit data buses, read and write control li...[Details]
UDN2916LB is a two-phase stepper motor bipolar driver integrated circuit launched by SANKEN. It can drive dual-winding bipolar stepper motors and is particularly suitable for controlling dual-step ...[Details]
1 Introduction
The early stage control system used relay control. Due to the large number of stage equipment, the number of control elements is huge and the wiring is complicated. Therefore, th...[Details]
Designing with FPGA, DSP or microprocessor is a critical part of the design and also takes the most time. System-level designers can benefit greatly by focusing their main efforts on system desig...[Details]
3. Driving circuit design
The power driver uses a field effect tube, which is a field-controlled device with a capacitance effect between the gate and source, so it has high requirements for t...[Details]
