CONSTANT-TO- ALTERNATING SINUSOIDAL VOLTAGE CONVERTER Russian patent published in 2010 - IPC H02M7/501 

FIELD: electricity.

SUBSTANCE: to constant-to-alternating voltage converter containing the master generator the output of which is connected to input of frequency divider the outputs of which are connected to anodes of diodes, the cathodes of which are connected to gates of MOSFET transistors, the sinks of which are connected to taps of primary winding of power output transformer, the middle output of which is connected to positive pole of power source, there introduced is frequency divider consisting of two binary summation counters (2) and (5), two decoders/demultiplexers (3) and (4), diodes (7) and (8), and transistor inverter (6); at that, output of clock generator (1) is connected to inverting input of binary summation counter (2) the outputs of which are connected to address inputs of two decoders/demultiplexers (3) and (4), the inputs of which are connected to outputs of less significant digit of summation counter (5) and transistor inverter (6) respectively. State of summation counter (5) is determined with voltage pulses supplied to inverting input through diodes (7) and (8) respectively from outputs of decoders/ demultiplexers (3) and (4), which correspond to address code combination 1111.

EFFECT: improving the quality of shaped output voltage, larger reliability, smaller cost.
