Abstract :
The experience of designing switched mode power supplies (SMPS) for radar applications is demonstrated. Methods of solving the following problems are revealed: maintaining high quality output voltage of SMPS in a full range of changing destabilizing factors; reduction of electromagnetic interference (EMI) level; increasing efficiency and reliability; reducing the cost; designing multichannel SMPS with equivalent and independent channels; maintaining a high level of load currents; parallel operation of several SMPS. The principles of designing the resonant power supply for the microprocessor system of a multichannel radar with phased antenna lattice are considered. The features of designing multichannel SMPS for radio-receiving and transmitting devices are shown. The topology and main technical data of power supplies are adduced
