PURPOSE: An environmentally-friendly broadcasting device supplying high quality tuning electric power with a fast response characteristic is provided to minimize the amount of impulse and noise generated from an electric power system by supplying high quality power from a condenser which has a fast response characteristic compared to a storage battery. CONSTITUTION: A power supply unit(6) comprises at least one compensation capacitor(1), at least one capacitor(2), Zener diodes(4), and resistances(5). The compensation capacitor(s) and the capacitor(s) are connected either by an series connection or by a circuit separation, depending on the selected contact point of a noncontact relay(3). The Zener diodes and the resistances are connected in parallel with the capacitors. A DC power supplying unit(7) includes at least one power supply unit which is connected in parallel. |
