In an embodiment, a voltage amplifier is provided. In this voltage amplifier, a DC/DC boost converter converts an input DC voltage to an output DC voltage, which is higher than the input DC voltage. A DC/AC converter connected to the DC/DC boost converter converts the output DC voltage to an AC pulse-train. A voltage multiplier connected to the DC/AC converter converts the AC pulse-train to an amplified output DC voltage that is higher than the AC pulse-train. A discharger connected to the voltage multiplier can discharge the amplified output DC voltage.
