Power supplies - rate 31,490 rub. from Specialist, training 16 academic hours, date of May 15, 2023.

Power supply - a device designed to provide power to an electrical appliance energy, subject to the requirements of its parameters: voltage, current by converting the energy of other power supplies. The power supply can be integrated into the overall circuit (usually in simple devices) and implemented as a separate module (power supply).

The power source must provide:

- Ensuring power transmission - the power source must ensure the transmission of the specified power with minimal losses and compliance with the specified output characteristics.
- Voltage waveform conversion - conversion of alternating voltage to direct voltage, and vice versa, as well as frequency conversion, generation of voltage pulses, etc. Most often, it is necessary to convert alternating power frequency voltage to direct voltage.
- Conversion of the voltage value - both increasing and decreasing. Often a set of several voltages of different values ​​is needed to power different circuits.
- Stabilization - voltage, current and other parameters at the output of the power source must lie within certain limits, depending on its purpose under the influence of a large number of destabilizing factors: changes in input voltage, load current, etc. Further. Most often, voltage stabilization at the load is necessary, but sometimes current stabilization is necessary.

- Protection - voltage or load current in the event of a malfunction (for example, short circuit) of any circuits may exceed permissible limits and disable the device or the power source itself.
- Adjustment - during operation, it may be necessary to change any parameters of the supply voltage to ensure proper operation of the equipment.

Most often, power supplies are faced with the task of converting electricity from an industrial-frequency AC network to direct current. The two most common power supply designs are transformer and switching power supplies.

The advanced training program is designed for engineering and technical workers with higher professional education involved in circuit design, design and technology design for radio electronics, electronic computer equipment, automation and control systems, etc. for various purposes, as well as for middle managers of project organizations.

Students who successfully complete the training are issued a certificate of advanced training in the established form.
