Voltage Controllers

Voltage controllers are electronic devices that control a circuit’s consistent voltage and are designed to provide voltage management applications. They convert a consistent voltage input into a variable voltage output transmitted to resistive loads. Like voltage regulators, they also control the voltage output. However, voltage regulators function slightly differently as they generate variable outputs like variable voltage or act like switches for power diversion. 

Furthermore, voltage controllers share similarities with voltage converters in all their integrated circuitry. Additionally, these controllers feature AC-DC or DC-DC conversion types.

Types of Voltage Controller

These controllers are broadly categorised into single-phase and three-phase voltage controllers. 

  • Single-Phase: They are designed to control power supplies ranging from up to 230 RMS at 50–60 Hz.
  • Three-Phase: They are made to control 400 RMS voltage and a 50–60 Hz power supply. 

Other types include:

  • PWM controller
  • Buck controller
  • Step-down voltage controller
  • Boost controller
  • Flyback controller.

What are the Typical Applications of a Voltage Controller?

Voltage controllers are widely suitable for driving MOSFETs with a wide range of applications that necessitate power and voltage management. They are commonly found in:

BM1P062FJ-E2, ROHM

The PWM type DC/DC converter (BM1Pxxx) for AC/DC provide an optimum system for all products that include an electrical outlet. BM1Pxxx supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters. BM1Pxxx built in a HV starter circuit that tolerates 650V, it contributes to low-power consumption. With switching MOSFET and current detection resistors as external devices, a higher degree of design freedom is achieved. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. PWM current mode method Frequency Hopping function Burst operation / Frequency reduction function when load is light Built-in 650V start circuit VCC pin under voltage protection VCC pin over voltage protection CS pin Open protection CS pin Leading-Edge-Blanking function Per-cycle over current protection circuit Current protection with AC voltage compensation
