In Wince, I created a modal dialog box Dialog2 in Dialog1. CDialogTime m_DiaTime; m_DiaTime.DoModal(); Then I used the following functions in Dialog2 to close it. (1) OnOK(); (2) DestroyWindow(); (3) ...
The working principle of a linear regulator is to use a voltage-controlled current source to force a fixed voltage at the output of the regulator. The control circuit continuously monitors (senses) th...
It is more sympathetic and lamentable. Although he may not be very good at business, as for animation, my first thought is, can China compare with foreign Westerners in creativity? Maybe there is no h...
Hello everyone, I have made a small system, using AT28C64B as program memory. How can I encrypt the chip to protect my program from being stolen? Some programmers can encrypt, but since it can be encr...

For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
Instrument stepper motor
The stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non...[Details]
