Claims

[Scope of utility model registration request]

In a stabilized power supply device using the thyristor phase control method, the main thyristor is fired from the start point of the half-thyristor (zero volts), turned off in the middle of the half-recycle, and then the main power transformer and the next winding are turned off. A thyristor-controlled stabilized power supply device characterized by reducing power loss.
