<p>PURPOSE:To start a power source even if the desired output cannot be obtained from a storage battery by providing a small capacity self-excited auxiliary power source which inputs a high voltage power. CONSTITUTION:If a power source 1 cannot be started by the output of a storage battery 2, a low voltage power is supplied through a diode 4 to a capacitor 6 when a high voltage is not applied to a self-excited auxiliary power source 3. When the charging voltage of the capacitor 6 comes the prescribed 4 value, a voltage is supplied to the gate circuit of the power source 1 to start the power source 1. When the power source 1 is started, a low voltage power of the output is applied through a diode 5 to the gate circuit of the power source 1. The battery 1 is charged by the output of the power source 1 to prepare for the power interruption of the power source 1. If the battery 2 is sufficiently charged, the power source 1 is started by the battery 2.</p> |
