Power supply source for an electric heating system. The invention relates to power engineering, in particular to electric heating systems for residential and other buildings. The power supply source for an electric heating system comprises an inductance coil (1), which is connected to a load circuit (4) and is connected to a primary source (3) of electrical energy with the possibility of periodic connection of one of the ends of said coil (9) to one of the terminals of the primary source (3) of electrical energy via an electronic switch (6), and a generator (8) of pulses of single polarity, the output of which generator is connected to the input of the electronic switch (6). According to the invention, the second end (10) of the inductance coil (1) is connected to the second terminal of the primary source (3) of electrical energy via a second electronic switch (7), the input of which is connected to the output of said generator (8) of pulses of single polarity so as to ensure synchronized operation of said electronic switches (6, 7). The result which can be achieved consists in increasing the energy conversion ratio. |
