A pulsed power supply is a device that emits high voltages of several kilovolts during extremely short time scales.
The main characteristic of a pulsed power supply is that the voltage rise time is extremely fast, yet the high voltage output can be repeated at high frequencies (~100 kHz).
In addition, since the output is not continuous and there is a cooling time, the temperature rise of the device itself and the space can be suppressed.
Pulsed power supplies are used in academic and industrial fields that require high output voltages (e.g., power supplies for plasma generation).
Pulsed power supplies are widely used as power supplies for plasma-applied equipment.
They are used to apply charged particles such as light, electrons, and ions generated from plasma to objects, and for sterilization and water treatment using shock wave generation from pulsed discharge.
In addition, in order to drive high-power, high-efficiency lasers such as excimer lasers, a short-duration, high-power pulsed power supply is required because the laser gas needs to be excited instantaneously. There are also applications for use in driving such high-power lasers.
AC power input to a pulse power supply is first converted to DC by a rectifier circuit, and then charged in the electrolytic capacitors built into the power supply.
The charged power is converted into pulses by insulated gate bipolar transistors (IGBTs). IGBTs are a type of power semiconductor that enables high-speed switching of large amounts of power.
In addition to IGBTs, an element called a saturable reactor is used. The saturable reactor has a high magnetic permeability in the low current range and does not allow current to pass through. When the current increases and the magnetic flux density exceeds a certain level, the reactor is able to allow current to pass through.
The relationship between the charging speed of this capacitor and the saturation value of the saturable reactor determines the charging voltage characteristics of the circuit.
Furthermore, the generated pulse voltage is induced in the saturable reactor provided in the next stage.
If the inductance of this reactor is smaller than that of the first stage, a shorter pulse voltage can be generated. If shorter pulses are required, a multistage supersaturated reactor is provided.
Using such a magnetic compression circuit, short pulses compressed down to less than 100 ns can be output to the load.
