CHAPTER 1 INTRODUCTION
1.1 DESCRIPTION
The Series 500A/102A/152A/202A are High Voltage Switching Power Supplies designed
specifically for charging capacitors in laser systems and other pulsed power applications.
The 500A provides 500 J/s. the102A is 1000 J/s, 152A is 1,500 J/s, and the 202A
provides 2000 J/s of average power and can be paralleled indefinitely for higher total
system power. TDK-Lambda Americas Inc. also offers the 402 Series, 802 Series, and
303 Series rated at 4,000, 8,000 and 30,000 J/s respectively.
The 500A/102A/152A/202A power supplies incorporate a new high-frequency IGBT
parallel resonant inverter topology for efficient generation of the output power. A high-
performance control module precisely regulates the output voltage, automatically
compensating for line, load, temperature, and rep rate variations. Normal external fault
conditions such as line dropout open or short circuit load, HV arc and over-temperature
will not damage the unit. The latest development in the parallel resonant inverter
topology and control circuitry also drastically improves pulse-to-pulse repeatability by
reducing the ripple or “bucket effect” even at very high pulse repetition frequencies. The
output voltages of the 500A/102A/152A/202A supplies are fully adjustable over each
range.
