Oscillators: CPPLC7-A7BP-110.0PD application field and working principle

Oscillators are electronic circuits that generate steady periodic motion, mainly in the form of alternating current or alternating voltage. The most commonly used oscillators are based on the LC (inductance-capacitance) circuit. When an AC power source connected to the LC circuit, the capacitor is charged and discharged periodically, which causes the alternating current to run between the two ends of the circuit.

The CPPLC7-A7BP-110.0PD oscillator is a special LC oscillator made by the CPP Corporation. It is a broadband high-quality wave generator which is optimally designed for frequency control applications from over a wide range of output frequencies. This CPPLC7-A7BP-110.0PD contains two exterior parts: a Power Supply unit and a Tuning Box unit. The power supply unit is composed of a bridge rectifier, a frequency shaping amplifier module, a voltage regulator module, and a protection module; while the tuning box unit is composed of a tuning resistor, an inductance, a capacitance and some special coil protected by a cover.

The CPPLC7-A7BP-110.0PD oscillator is mainly applicable for equipment such as frequency tuning relay, electric meter, frequency converter, etc. In general, this high-quality wave generator is applied based on the following working principle. Firstly, the frequency shaping amplifier module can receive the alternating current of the rectifier and then convert it to a stable voltage which makes the phase shifts on the sine wave become 90 degrees. Secondly, the phase shifting signal from the amplifier is fed to the Tuning Box unit, and then the output waveform is generated owing to the changes in the parameters of resistor, inductance, and capacitance.

In conclusion, CPPLC7-A7BP-110.0PD is an oscillator manufactured by the CPP Corporation which is mainly applicable for electric equipment such as frequency tuning relay, electric meter, frequency converter, etc. It contains two exterior parts, a Power Supply unit and a Tuning Box unit. The working principle of this oscillator is based on the frequency shaping amplifier module converting the alternating current to a stable voltage and the Tuning Box unit generating the output waveform with the changes in the parameters of resistor, inductance, and capacitance.
