A voltage of the second voltage supply is higher than a voltage of the first voltage supply.

A voltage translator is provided that translates a lower voltage to a higher voltage, for example, a 3.3V voltage to a 5.0V voltage.

Rated voltage (V)/minimum voltage (V), end of charge voltage (V) …

A voltage regulator generates regulated voltage from an input voltage.

The voltage converter converts the detected voltage to a lower voltage Vref.

A second voltage converter converts the second dc voltage into an ac voltage, raises a voltage level of the converted ac voltage, and provides the raised ac voltage to a load.

The inclined waveform voltage is generated by switching the lowest voltage in the inclined waveform voltage between a first voltage and a second voltage having a voltage value lower than the first voltage.

The voltage comparison unit compares a voltage detected by the voltage detection unit and a reference voltage.

The bias voltage is a fixed voltage.

The difference between the first voltage and the voltage reached by the first falling voltage is made greater than the difference between the second voltage and the voltage reached by the second falling voltage.

The first voltage is applied between the second voltage and the reading voltage.

A voltage to frequency converter creates a voltage on a node, the voltage repeatedly varying between about the reference voltage and about the second voltage.

The driver supplies the electrode with at least one of a bias voltage, a reference voltage of the bias voltage, a sustain voltage, and a reference voltage of the sustain voltage.

In order to convert the input voltage into an applied output voltage, the negative feedback voltage is proportional to the output voltage.

The voltage detection unit detects a voltage value of the working voltage.
